An opening is any space or gap within a barrier. An opening is meaningful so far it is in a barrier. The opening could be a ‘puncture’, surrounded by the barrier on all its sides, or a cleavage between two barriers. Openings are also called ports, as across the opening one can ‘board’ a new system. An opening is called a passageway, as this is the only way, one can, transit a territory.

An opening can never be larger or equal to a barrier within which it resides. All physical openings have a finite size. A smaller opening makes a barrier system very evident, whereas a large opening or multiple openings make barriers less effective. Opening systems are also ineffective in transparent, translucent or frequently interrupted (broken or discontinuous) barriers. A room with a lattice wall all around has no need for a window, or a glass cabin has no need for an opaque (solid) door.

Openings are defined by superlative structures to denote the presence and control the activities occurring through it. The superlative structures over passageways such as Gates, Gateways or Doorways are large in size and very distinctively formed. Formal structures have shutter devices whereas symbolic structures are simple openings. Nominally a passage is a linear entity, and so do the gates have singular passage. Cross junctions of passages require four or more sided gates.

Multiple Openings

The superlative structures function as control Gateways over openings. Such openings’ control the transactions, by way of the size, volume, temporal rate of passage and the qualitative nature of things. The transactions across the openings are of two ways, exit and entry types, and so the controls are also dualistic.

Gates with minimal structure

All communication channels have Gateways, from where the traffic gets diverted to appropriate channels and portals where divergent traffic gets ‘routed. These gateways register size of individual transactions, time of arrival-departure and source-destination of traffic. But most importantly there are ‘protocols’ that check whether the destined item has reached or not.

Surveillance gates or ports

In buildings openings like Gates, Doors, Windows, Ventilators, Gaps, Cracks, Crevices and Punctures all denote physical entities, but there are innumerable imperceptible points where observance and control occur. The sensors, cameras, readers, etc., are concealed, made minute in size and programmed so that ‘Gates’ structures are not imminent.

Openings in buildings have facilities for allowing sunlight, air, sounds and for framing view of the outside. The openings also create architectural patterns, compositions through scaling and proportioning, endow specific style character, affinities and identities. The openings occur in a barrier system as a connecting threshold or edge between two distinct worlds, but their own presence assumes many different guises. An opening is designed to be a distinct medium investing a nature of relationship between spatial domains.

Gates were entry and exit points to a fortified settlement. Goods, men and livestock passed through this point, so it became a check-post not only for control, but assessment and collection of revenue. Gates had structures that housed the sentries and revenue officials. Gates being a sensitive point in terms of security and transactions, a regular set up for intelligence collection (Kotwali in India) was established here.

Fortified areas were usually very small and with limited resources. To control the population inside the fortified area, right of habitation was restricted to select few. All outsiders and their livestock were allowed to stay inside, from sun up to sun down periods only. This required a time keeping and a signalling system, usually enforced from the gate area. The signalling systems included cannons, guns, flags, smoke signals, light torches, conch shells, bells, drums, nagara, shehnais, nadswarams, trumpets, bugles, echo reflector walls, etc. In each case the solutions to house them were equally varied.

Gates and Gateways are structures that denote a change in the environment. Such structures are real, or indicative metaphysical entities. Gates have been a symbol of power, protection, and prosperity. The gate is a point of transition into a world that is civilized, peaceful and ordered, unlike the chaos, fear and uncertainty outside it.

Gates as symbol of power

Symbolic gates are structures with large openings at the ground level, though high plinth structures with steps are common. Gates as the symbolic structure mark the domain itself, or an opening into it. Such gates also project abstract ‘dominance’ or extent, even when definitions of the domain may be weak or not existent.

Formal gates function as controller entry or exit and so have shutters. Such gates are usually in fortified or bounded areas. Such gates need functional shutters, but the size of gate would require equally large sized shutters. This has been a technological restriction, so in spite of very large gate and architecture of opening actual ‘door’ sizes are usually smaller. The large size shutters, even, if functional in terms of opening and closing, required small gap for passage of a person or delivery of a message and objects.

Estate Gates are associated with landed assets such as complex of buildings, temple or residential complexes, army cantonments, royal animal yards, jails, educational institutes, graveyards, burning ghats, river ghats, ports, markets and parks. Gated communities have their own domain of privacy and security. Such communities actually begin to be status symbol or sign of exclusivity.  Modern gated community flourish with means or surveillance and communication. These two major modalities can work, if only part of the larger framework.

Memorial Gates are erected at important locations and denote important sections of town. Mid Town Gates also occur to signify important sections of the town.

Gates, monuments and other edifices have been associated with points where an acute change of environment exists or is required to be enforced or indicated. Gates on state boundaries signify the change in a political authority, though across the border, geographic, climatic or social change may not really occur. A gate structure like Char Minar does not register any change before or across it.

A Ghanta Ghar, Bell or Clock Tower is designed as a gate like structure that signifies an important location or landmark in an urban landscape but does not mark a different environment on the other side. Gates erected as a memorial can be anywhere in town, at cross roads, edge of the land or water or in parks.

Gateway of India, Mumbai (Bombay) India

A Gateway is an inclusive definition of a gate. A gateway is a gate, but has the sense of passage in it, giving an idea of depth. The depth is created by the deeper section of the gate structure, or by dual or multiple gates with an intermediate passage.

Bhadra Fort, Ahmedabad, India, -Multiple gates

The depth due to the elongated structure or the passage enforces the discipline and place for intervening changes. Gates are nominally two-way structures that are have single passage across it, but some gateways are four-way structures with crossing passages. Gateways have one, three or five passages, if more it expresses a colonnade or arcade.

A gateway stands alone or is part of a wall structure of a fort, but in both the cases as a very significant entity due its scale and proportions. Formal gates function as controller entry or exit and so have shutters. Such gates are usually in fortified or bounded areas. These gates need functional shutters. A gateway structure, however, could be so large that no gate of such a size (doorway) is technologically feasible, and even if feasible, it is difficult to operate it frequently. Such gateways have doors of manageable size, or the large doors are inset with small doors just sufficient for one person entry.

Gateways structures denote a change in the environment. Such structures are real, or indicative metaphysical entities. Gates have been a symbol of power, protection, and prosperity. A gateway is a point of transition into a world that is civilized, peaceful and ordered, unlike the chaos, fear and uncertainty outside it.

Gates are conceived to be very significant, and naturally receive all the due patronage. The functional importance and patronage of the society for the gate are often so overwhelming that it becomes a superlative entity with more grandiose than the king’s palace or temple of God.
