HISTORIC CITY CENTERS UNDER THREAT: THE
CASE OF SHARJAH, UAE
SPACE SYNTAX
UNESCO selected the Emirate of Sharjah as the cultural capital
of the Arab World.
 Sharjah’s historic center
PROBLEMS
 traffic congestion
 environmental degradation
 unattractive for visitors and inhabitants.
TO
 reverse any further degradation of the historic city center
 achieve economic and social gains
 conserve the environment
 preserve the cultural heritage.
THE CHALLENGE
 revitalizing historic Sharjah by
Identifying ….understanding ….providing
solutions to problems that have emerged through its recent rapid
growth.
The main goal is
Put future development strategy
urban design guidelines for revitalizing the historic core.
 Space Syntax is used
AS a diagnostic tool
TO understand how the history and evolution
of the city’s structure after modernization
had led to patterns of
density
land use
socio-economic settlement.
ARIAL VIEW OF SHARJAH HISTORICAL CORE
 historic urban development thus has shared three main
characteristics with other port cities of the Gulf.
1. it naturally fit in and was open to a body of water.
2. it was protected from the desert edge by a wall and a fort.
3. it maintained a diverse and multi-functional life connected
to the Waterfront.

METHODOLOGY
 The methodology included analyses at two different scales
1- city scale spatial analysis
segment map for the entire city by space syntax.
integration and choice values
to see how the study area of the historic center of the town is related to the
city in general

The streets that create the gridal system is

The analysis local choice is similar to the
local integration analysis in that the local
centers are also highlighted in this map. One
more major difference is the higher
integration value of the historical core and its
surroundings
suggesting the potential of this area.
The modern developments towards the
inlands almost totally lack any local centers,
which demonstrates how the modern
developments do not follow a similar pattern
ANALYSIS AT THE HISTORICAL CENTER
SPATIAL ANALYSIS OF THE STUDY AREA
 A ‘spatial modeling’ study has been used to
assess the accessibility of linkages through
the study area. Space syntax method has
been used to analyze the spatial
configuration of Sharjah Historic area. A
segment map has been constructed showing
all the accessible space in the study area.
The segment map has been processed using
the DepthmapX v.28 software and integration
and choice values for each line on the map
 When segment maps are analyzed for choice
value at the global level, the streets
surrounding the heritage area as well as the
Hisn Avenue show similar characteristics as
the heritage area is less integrated. At the
local level (r100), the choice value for
Sharjah heritage area located within the
reconstructed historic wall is higher then the
rest of the historic area.

ANALYSIS OF THE RELATION BETWEEN MOVEMENT
PATTERNS AND SPATIAL CONFIGURATION
 The relation is clear between the space syntax
analysis and the vehicle
 The relation is very low between the space syntax
analysis and the pedestrian movement
fact that there is quite a lot of pedestrian movement in
the area
Its related to the activities that the area houses such as
the old mosques
the major banks
Old market
Moreover, the dominance of male movement indicate
that
land use characteristics
religion related uses
ANALYSIS
 The port is a centre of international commerce
in the region.
 Historically developed along the waterfront up
until 1970s
 modern planning that pulled the urban growth
toward the inland.
 The University town and the residential
neighborhoods around the ancient site are the
first modern developments.
 These developments inevitably
changed the social and spatial structure of historic
 there is a vehicular road between the sea and
these shopping units.
 The materials were unloaded from the ships
directly to the depot area of the shops.
 Solution
 restore the link between the souk and
waterfront,
 recreate and strengthen a continuance of
waterfront to the heritage area
 turn lead to an increase in the vitality of the
center
 create an economically productive historic core.
 since they are one big
continuous piece
 they cut the breeze coming
from the sea to cool of the
streets and make the space
attractive for pedestrians.
future design proposal
 the area should have land uses that promote active
uses such as
 services
 accommodation
 Entertainment
 that would also help protect the vitality of the
heritage area
 the wall separates the space defined by the wall from
the rest of the heritage area and in turn adds to the
segregation of the historic core from the rest of the
city
 very similar to the cases of other Islamic cities such as Jeddah….
 the city developed based on modern urban planning principles
focusing on the primacy of vehicular traffic the scale of the
context increased.
 The historic fabric of these cities has changed as a result of
major program of road building
physical reshaping
which shifted the structure of the integration core
weakened the connection of the historic centers.
So the historic core has a structure itself but as the city gets
developed this structure gets disconnected from the city and the
complex of local centers and sub-centers fade away.
Thus we can conclude that, as stated in earlier studies, the
problems faced in historic city centers are not local but global and
the task is
NOT TO REDESIGN BUT TO
RECONNECT
