this PowerPoint presentation contains all you should know about Islamic architecture. this features the history, architectural character, examples of Islamic structures, and the contemporary Islamic architects. Best for architecture students studying History of Architecture 3.
2. HISTORY
Islam originated in Arabia. In 610 the
angel Gabriel is said to have appeared to
Mohammed in Mecca and expounded the
revelation of God, or Allah.
These revelations were collected into a
holy book, the Qur’an, which expressed in
Arabic the message of Islam, a word
signifying submission to the will of Allah.
3. By 661 Islamic armies had swept through what
is today Iran, Iraq, Israel, Syria, and Egypt, and
they then moved across the North African
coast to enter Spain in 711.
From Spain they pushed northward into
France, where forces led by Charles Martel
stopped their European expansion in 732 at
the battle of Tours. Islamic settlers remained in
central and southern Spain until 1492,
however, and their armies continued to batter
the southern border of the Byzantine Empire
until they finally conquered Constantinople in
1453.
4. Through trade, Islamic dynasties made contact with
China and India, where their religion would
eventually take root.
With military conquest came economic, social, and
cultural dominance as Islamic customs and the
Arabic language replaced surviving Roman
practices.
The heady mix of learned men from Islamic and
Jewish traditions, sometimes joined by Christian
theologians, contributed to a highly productive era in
the arts and sciences from the ninth through
sixteenth centuries.
5. SOCIETY
• Tribal groups
• Public life was reserved for men (women had a
secondary role - for domestic and agricultural work)
• Christians and Jews ("people of the book“) were
given the freedom of worship and self-government
• Many of the conquered cities were already centers
of learning
• Muslims translated into Arabic many scholarly
writings from Greek, Persian and Indian
• Rulers and scholars were interested in
mathematics, astronomy, geography, medicine,
philosophy and science
6. RELIGION
• Complete philosophy of life and government
• One god Allah, Muhammad is the prophet
• Faith is held to be Allah's will for creation
• Acceptance of the transitory nature of earthly life
• Personal humility
• Abhorrence of image worship
KORAN
• Muhammad wrote down the words of angels who
brought him messages from Allah
• After his death, these accounts were compiled
into a holy book
• Speaks of the power of Allah, to accept his will
and to praise him
7. ISLAM’S FIVE BASIC TRUTHS or DUTIES
• To believe on the oneness of God, and that
Mohammed was the messenger of God;
• To pray five times daily;
• To fast from sunrise to sunset during the month
of Ramadan
• To give alms to the poor;
• and To make at least one pilgrimage to
Mecca, wealth and permitting.
*Also jihad or holy war is sometimes added as a pillar
to spread the faith and defend it from attack
8. ISLAMIC ARCHITECTURE
• Islamic architecture comprises the architectural styles of buildings
associated with Islam.
• Encompasses both secular and religious styles from the early history
of Islam to the present day.
• Islamic architecture was influenced by:
Roman
Byzantine
Persian
Mesopotamian
and all other lands which the Muslims conquered in the
seventh and eighth centuries.
• In the east, it was also influenced by Chinese and Indian architecture
as Islam spread to Southeast Asia.
9. • it developed distinct characteristics in
the form of buildings, and the decoration
of surfaces with Islamic calligraphy and
geometric and interlace patterned
ornament.
• New architectural elements like
cylindrical minarets, pointed arch,
muqarnas, arabesque, multifoil were
invented.
10. • The principal Islamic architectural types
for large or public buildings are: the
Mosque, the Tomb, the Palace and the
Fort.
• From these four types, the vocabulary of
Islamic architecture is derived and used
for other buildings such as public baths,
fountains and domestic architecture.
11. From the eighth to the 11th century, Islamic
architectural styles were influenced by two
different ancient traditions:
1. Greco-Roman tradition:
In particular, the regions of the newly
conquered Byzantine Empire (Southwestern
Anatolia, Syria, Egypt and the Maghreb)
supplied architects, masons, mosaicists and other
craftsmen to the new Islamic rulers.
These artisans were trained in Byzantine
architecture and decorative arts, and continued
building and decorating in Byzantine style, which
had developed out of Hellenistic and ancient
Roman architecture.
INFLUENCES
2. Eastern tradition:
Mesopotamia and Persia, despite adopting
elements of Hellenistic and Roman representative
style, retained their independent architectural
traditions, which derived from Sasanian
architecture and its predecessors.
12. INFLUENCES
Some features caused by The transition process between late Antiquity, or post-
classical, and Islamic architecture:
1. The existence of a linear development within the Islamic architecture;
2. the existence of an inter- and intracultural hierarchy of styles;
3. questions of cultural authenticity and its delineation
The Umayyads played a crucial role in this process of transforming and thereby enriching the
existing architectural traditions, or, in a more general sense, of the visual culture of the nascent
Islamic society.
13. ARCHITECTURAL CHARACTERISTICS
Some characteristics of Islamic architecture were inherited from pre-Islamic architecture
of that region while some characteristics like:
minarets,
muqarnas,
arabesque,
Islamic geometric pattern,
pointed arch,
multifoil arch,
onion dome ,
and pointed dome developed later.
14. MINARET
Minaret is a type of tower typically built
into or adjacent to mosques. Minarets
serve multiple purposes. While they
provide a visual focal point, they are
generally used for the Muslim call to
prayer (adhan). The basic form of a
minaret includes a base, shaft, a cap
and head. They are generally a tall
spire with a conical or onion-shaped
crown.
Different types of Minaret.
1. Iraq 2. Morocco 3. Turkey
4. India, 5. Egypt 6. Asia.
15. MUQARNAS
• The architectural element of muqarnas
developed in northeastern Iran and the
Maghreb around the middle of the 10th
century.
• The ornament is created by the
geometric subdivision of a vaulting
structure into miniature, superimposed
pointed-arch substructures, also known
as "honeycomb", or "stalactite" vaults.
• Made from different materials like stone,
brick, wood or stucco, its use in
architecture spread over the entire
Islamic world. In the Islamic West,
muqarnas are also used to adorn the
outside of a dome, cupola, or similar
structure, while in the East is more
limited to the interior face of a vault.

17. ARABESQUE
The arabesque is a form of artistic
decoration consisting of "surface
decorations based on rhythmic linear
patterns of scrolling and interlacing foliage,
tendrils" or plain lines, often combined with
other elements.
Foliate ornament, used in the Islamic world,
typically using leaves, derived from stylized
half-palmettes, which were combined with
spiraling stems
18. ISLAMIC GEOMETRIC PATTERN
• Islamic decoration, which tends to
avoid using figurative images, makes
frequent use of geometric patterns
which have developed over the
centuries.
• The geometric designs in Islamic art
are often built on combinations of
repeated squares and circles, which
may be overlapped and interlaced, as
can arabesques (with which they are
often combined), to form intricate and
complex patterns, including a wide
variety of tessellations. These may
constitute the entire decoration, may
form a framework for floral or
calligraphic embellishments, or may
retreat into the background around
other motifs.
20. ARCHES
The horseshoe arch became a popular
feature in Islamic structures. Some
suggest the Muslims acquired this from
the Visigoths in Spain but they may
have obtained it from Syria and Persia
where the horseshoe arch had been in
use by the Byzantines.
In Moorish architecture, the curvature
of the horseshoe arch is much more
accentuated. Furthermore, alternating
colors were added to accentuate the
effect of its shape.
26. ARCHITECTURAL CHARACTERISTICS
Other characteristics:
Paradise garden
Afif-Abad Garden, Shiraz
Gardens and water have for many centuries
played an essential role in Islamic culture, and
are often compared to the garden of Paradise.
Large Paradise gardens are also found at the
Taj Mahal (Agra), and at Humayun's Tomb
(New Delhi), in India; the Shalimar Gardens
(Lahore, Pakistan) or at the Alhambra and
Generalife in Granada, Spain
27. ARCHITECTURAL CHARACTERISTICS
Other characteristics:
Courtyard (Sehan)
The traditional Islamic courtyard, a sehan
(Arabic: صحن ), is found in secular and religious
structures.
The Great Mosque of Kairouan, with a large courtyard
(sehan) surrounded by arcades, Kairouan, Tunisia
28. ARCHITECTURAL CHARACTERISTICS
Other characteristics:
Courtyard (Sehan) functions:
1. When within a residence or other secular
building is a private courtyard and walled
garden. It is used for: the aesthetics of plants,
water, architectural elements, and natural light;
for cooler space with fountains and shade, and
source of breezes into the structure, during
summer heat; and a protected and proscribed
place where the women of the house need not
be covered in the hijab clothing traditionally
necessary in public.
2. A sehan—courtyard is in within almost every
mosque in Islamic architecture. The courtyards
are open to the sky and surrounded on all sides
by structures with halls and rooms, and often a
shaded semi-open arcade. Sehans usually
feature a centrally positioned ritual cleansing
pool under an open domed pavilion called a
howz. A mosque courtyard is used for
performing ablutions, and a 'patio' for rest or
gathering.
29. ARCHITECTURAL CHARACTERISTICS
Other characteristics:
Vaulting
• Umayyad diaphragm arches and barrel vaults
Umayyad period buildings show a
mixture of ancient Roman and
Persian architectural traditions.
Diaphragm arches with linteled
ceilings made of wood or stone
beams, or, alternatively, with barrel
vaults, were known in the Levant
since the classical and Nabatean
period.
31. ARCHITECTURAL CHARACTERISTICS
Other characteristics:
Vaulting
• Spain (al-Andaluz)
The double-arched system of
arcades of the Mosque–Cathedral of
Córdoba is generally considered to
be derived from Roman aqueducts
like the nearby aqueduct of Los
Milagros. Columns are connected
by horseshoe arches, and support
pillars of brickwork, which are in
turn interconnected by semicircular
arches supporting the flat
timberwork ceiling.

33. ARCHITECTURAL CHARACTERISTICS
Other characteristics:
Vaulting
• Squinches
The system of squinches, which is
a construction filling in the upper
angles of a square room so as to
form a base to receive an octagonal
or spherical dome, was already
known in Sasanian architecture.
Squinches may be formed by
masonry built out from the angle in
corbelled courses, by filling the
corner with a vise placed
diagonally, or by building an arch or
a number of corbelled arches
diagonally across the corner. Dome of the Fire temple of Harpak in Abyaneh
35. ARCHITECTURAL FORMS
• Notable Islamic architectural types include the early Abbasid
buildings, T-Type mosques, and the central-dome mosques of
Anatolia.
• Arab-plan or hypostyle mosques are the earliest type of
mosques, pioneered under the Umayyad Dynasty. These
mosques are square or rectangular in plan with an enclosed
courtyard and a covered prayer hall.
• The Ottomans introduced central dome mosques in the 15th
century and have a large dome centered over the prayer hall.
In addition to having one large dome at the center, there are
often smaller domes that exist off-center over the prayer hall
or throughout the rest of the mosque, where prayer is not
performed. This style was heavily influenced by the Byzantine
religious architecture with its use of large central domes.

36. SPECIFIC ARCHITECTURAL ELEMENTS
Islamic architecture may be identified with the following design
elements, which were inherited from the first mosque buildings
(originally a feature of the Masjid al-Nabawi).
Al-Masjid an-Nabawī (622 ad)
Location: Medina, Hejaz, Saudi Arabia
• Minarets or towers
• Iwan - rectangular hall or space
• Mihrab or prayer niche on an inside wall indicating
the direction to Mecca.
• Domes and Cupolas
• Pishtaq is the formal gateway to the iwan
• Balconies are a common feature of Islamic domestic
architecture due to the warm climates in most
countries
• Capitals are the upper part or crowing feature of a
column or pilaster.
37. ISLAMIC STRUCTURES: EARLY SHRINES AND PALACES
• DOME OF THE ROCK (687-91)
Profile
- Located in the Old City of Jerusalem
- Ordered to be constructed by Umayyad Caliph Abd al-Malik
- The original dome collapsed in 1015 and was rebuilt in 1022-23.
- Style : Umayyad , Abbasid, Ottoman
- Earliest archaeologically-attested religious structure to be built by a
Muslim ruler and the building’s inscriptions contain the earliest
epigraphic proclamations of Islam and of prophet Muhammad.
- Structure is basically octagonal
- Capped by a dome, approximately 20m (66ft), mounted on an
elevated drum standing on 16 supports (4 tiers and 12 columns)
38. • DOME OF THE ROCK (687-91)
Its location on Mount Moriah was sacred to
the Jews, both as the site on which Abraham
had offered his son Isaac as a sacrifice to the
Lord and as the location of Solomon’s Temple.
Muslims honored it for Abraham’s presence,
but also venerated it as the place from which
Mohammed ascended in his night journey to
paradise.
39. • DOME OF THE ROCK (687-91)
At the center of the Dome of the Rock is a rock, under
which is a small cave with a single opening. The
shrine is carefully positioned around this rock, the
domed central portion enclosing the rock and a
concentric aisle permitting circumambulation.
The building’s form was probably derived from
Christian precedent. Constantine’s Church of the Holy
Sepulcher in Jerusalem had featured a similar
rotunda, and there were many centrally planned
domed churches throughout the Byzantine world.
Unlike most Byzantine domes, however, the structure
here is of wood.

Notas del editor
1- Conversion of the tribes to Islam was accompanied by an intense awakening of Arab fervor, and the courage and fighting skill of Arabic tribes, previously exploited by the Sassanian and Byzantine empires, was turned against these masters in a fury of rapid conquests, frequently aided by local contempt for the corruption associated with Byzantine rule.
3- Islamic policy toward conquered populations was generally one of accommodation. Islamic rule was often preferred by the natives of occupied lands to that of harsh Byzantine governors, and the multicultural society the invaders fostered provided a model of respectful interaction that the modern world might do well to rediscover.
