Urban Square

Urban Square:

• Urban square is an open public space used for

community gatherings

• The first urban formations appeared 6000 years ago

• City squares were established at the cross roads of

important trade routes

• Major places of worship were placed on squares, also

used as markets

• Served as an opportunity to exercise the power of

rulers with military processions and parades

The public space


Urban Square

Function of Squares:

• Creates a gathering place for the

people

• Providing them with a shelter

against the traffic

• Freeing them from the tension of

rushing through the web of street

• Represents as a psychological

parking place within the civic

landscape

Very ‘heart’ of city


Urban Square

Reasons for development of Squares:

‘Life in public’

• Climatic conditions

• Societal structure and psychological attitude of people

• led to a form of public life – and life in public

• Made street and square the natural locale for

community activities and representation


Urban Square

Factors that formulate the Square:

• On the relation between the forms

of the surrounding buildings

• On their uniformity or their variety

• On their absolute dimensions

• On relative proportions in

comparison with width and length

of the open area

• On the angle of entering the

streets

A hole or ‘w

hole’


Urban Square

Squares – A part of living organism

‘A Living organism

’

• A Square is never completed

• Some may vanish, be destroyed. Others may be

replaced and new ones added

• A square, an accumulation of important buildings in past

may have developed into comprehensible form now

• Elements of square such as

surrounding structures,

monuments are subjected to

flux of time


Urban Square

Reasons for changes in Square

‘A Living organism

’

• Physically through the erection of new buildings & the

alteration or destruction of old ones

• Through a modification of the building line

• Psychologically, through the different way in which each

generation experiences


Urban Square

The Archetypes

‘Three elements’

• Square consists of three space

confining elements

• Surrounding structures, floor and

the imaginary sphere of the sky

above

• Elements are decisively defined by the two-dimensional

layout of square

• These three factors that produce final three

dimensional effect may vary in themselves


Urban Square

Classification of Squares

‘Five types’

• Closed Square – Space self contained

• Dominated Square – Space directed

• Nuclear Square – Space formed around a centre

• Grouped Squares – Space units combined

• Amorphous Square – Space unlimited

• Squares doesn't represent only one pure type, but very

often bears the characteristics of two of these types


Urban Square

Closed Square:

‘Closed’

• It is a complete enclosure interrupted only by the streets

leading to it

• Primary element of any closed square is its layout of

regular geometrical form

• The repetition of identical houses or house types, facing

the enclosed area

• Spatial balance of the square will always be achieved

by the equation of horizontal & vertical forces

Urban Square

Closed Square:

‘Closed’

• Each façade fulfills a dual function

• On the one hand, it is part of an individual structure; on

the other hand, it forms part of a common urban spatial

order

• Continuity and context of the framing structures were

achieved by the Colonnade, arched arcades

• Yet, the inner courtyard with in a complex monumental

structure is not a square from the town planning view

Urban Square

The Dominated Square:

‘Dom

inated’

• Characterized by one individual structure or a group of

buildings towards which the open space is directed

• Surrounding structures are related to them

• Dominated building may be a church, a palace, a town

hall, an architecturally developed fountain, a theatre

• Usually the direction of a main street which opens into

the square establishes the axis towards the dominant

building

Paris


Urban Square


‘Dom

inated’

• Compels the spectator to move toward and to look at

the focal architecture

• Dominant square produces a directive of motion

• The dominated structure need not necessarily be

voluminous

• Very often it is merely a gate or an arch which may

dominate a whole square

• A fountain may also dominate a square it if constitutes

an entire front in with architecture, sculpture and water

Urban Square

The Nuclear Square:

‘Nuclear’

• Nuclear Square consists of a nucleus, a strong vertical

accent – a monument, a fountain, an obelisk

• It is powerful enough to charge the space around with a

tension that the impression of the square will be evoked

• It will tie the heterogeneous elements of the periphery

into one visual unit

• Dimensions of nuclear square are restricted as the

visual effect of the central monument is naturally limited

Urban Square

Grouped Squares:

‘Grouped’

• In Grouped Squares, Individual squares may be fused

organically and aesthetically into one comprehensive

whole

• Each unit - the individual square, represents an entity,

aesthetically self sufficient and yet part of a

comprehensive higher order

• A sequence of squares, different in size and form,

develops in only one direction, thus establishing a

straight axis


Urban Square

The Grouped Square:

‘Grouped’

Sequence of Squares developed in a straight axis

Imperial Fora, Rome


Urban Square

Grouped Squares:

‘Grouped’

• Or, in a non-axial organization, a smaller square opens

with one of its sides upon a larger square, so that the

individual axes of each square meet in a right angle

• Or, a group of three or more squares of different

shapes and proportions surround one dominant

building

• Or, two individual squares fall into a coherent pattern

although they are separated from each other by blocks

of houses, thoroughfares

The Amorphous Square:

‘Am

orphous’

• Amorphous is formless, unorganized, having no

specific shape

• It does not represent aesthetic qualities or artistic

possibilities

• However, if it shares some elements with the

previously analyzed squares it may appear like one of

them

• New York’s Washington square is not a closed square.

Its dimensions are so large


Urban Square


‘Am

orphous’

• Proportions of many of its surrounding structures are so

heterogeneous, so irregular, even contradictory

• Location and size of the small triumph arch are so

dissimilar to all the other given factors

• Unified impression

cannot result

• Disproportion in scale

destroys all aesthetic

possibilities New York’s Washington Square


Urban Square


‘Am

orphous’

• Place de l’Opera in Paris could not become a

“dominated” Square in spite of the monumental façade

of the imposing opera house

• Width of the Boulevard des Cupucines is running

through its off centre

• Presence of small structures like the entrance to the

Metro, scattered all over the area ruin any special effect

• These examples are “squares” from surveyor’s

viewpoint, although without any artistic impact
