Traditional Emirati architecture: barasti, coral stone and wind towers

Palm-frond screens, thick masonry and wind towers offered different answers to heat, glare and the need for shelter. Understanding how they worked also shows why conserving an old building means more than repairing its façade.

A palm-frond house and a coral-stone courtyard house approached summer differently: one let air pass through its lightweight enclosure; the other combined substantial walls with carefully placed openings. Traditional architecture in the Emirates was not a single building type, but a range of responses to materials, climate and household circumstances. To read it, look beyond the outline of a wind tower to the construction beneath it.

Arish and barasti: building with the date palm

العريش, arish, means a palm-frond shelter or house; barasti is another name commonly used for this form of construction. Skilled builders prepared and fastened the plant material; they did not simply pile branches into a roof. Woven or bound palm elements formed screens and coverings whose density could be adjusted for different uses.

The distinction mattered. An open screen admitted air while breaking up strong sunlight. A more closely woven panel offered greater enclosure; thicker arrangements could serve winter needs. Roof panels, privacy screens and ventilating walls therefore did not all require the same treatment. In hot, humid conditions, shade and moving air were particularly valuable.

Palm construction also required renewal as organic material deteriorated. Its survival as heritage depends partly on retaining the knowledge of how to make and replace its components. A newly made arish structure can demonstrate an inherited technique, but that is different from preserving an old building’s original material.

Coral stone, earth and the importance of the surface

Coastal masonry drew on marine materials. At Qasr Al Hosn, builders used coral and sea stone with mortar made from ground coral and crushed shells. These walls were composite constructions: the stone, the material joining it and the surface coating all mattered. Focusing only on the visible stone overlooks much of the building’s construction history.

Other coastal buildings used different combinations. The official Al Fahidi guide identifies shell stone, coral stone, gypsum and saruj, a traditional mortar material, among the neighbourhood’s building materials. There is no single recipe that can safely be applied to every historic wall.

In Al Ain, sun-dried mud brick is fundamental to the architecture of forts such as Al Jahili. Earth was a substantial building material, capable of forming high enclosing walls and towers, not merely a temporary substitute for stone. Al Jahili’s original complex combined a square fortified enclosure with a separate, tiered circular tower.

For a visitor, the useful question is not just “What is this made of?” Ask which parts carry weight, which protect the structure and which have been renewed. Conservation research in Al Ain records erosion, cracking and damage at wall tops alongside problems caused by later interventions. An apparently simple earthen wall can contain a complicated repair history.

Barjeel: how a wind tower works

البرجيل, barjeel, is a wind tower; the plural is barajeel. Rising above the roof, it catches air through elevated openings and directs it towards the room below. The tower is therefore part of a ventilation route, not a freestanding cooling ornament. The Al Fahidi guide describes openings on each side connected to a main room.

Air movement, rather than mechanical refrigeration, is the central principle. Research on Dubai’s wind towers explains how Gulf examples were adapted to deliver strong airflow in a humid climate. They worked alongside other features, including shaded air openings and roof terraces used to catch breezes. Calling them “early air conditioning” can be convenient shorthand, but should not imply modern temperature control.

These buildings also tell a history of exchange. Scholarship connects the spread of Dubai’s courtyard wind-tower houses with Persian merchant families, maritime commerce and the late nineteenth-century pearling economy. Their place in Emirati heritage reflects adaptation and local use within a connected Gulf world. The history of pearl diving helps explain that setting.

At Al Fahidi Historical Neighbourhood, look for the relationship between tower and room rather than photographing only the skyline. Where access permits, identify the opening beneath the shaft and consider how air could continue through the interior.

Forts: protection, residence and authority

Read fortifications through what they protected as well as how they looked. Qasr Al Hosn began as an eighteenth-century watchtower associated with coastal routes and a settlement around water sources. Successive additions transformed it into a fort and then a palace. The building records changing functions rather than one finished design. See the guide to Qasr Al Hosn for that longer history.

Al Jahili offers a different setting. Built between 1891 and 1898, it served both as an expression of authority and as a summer residence. Its later military occupation brought further buildings and alterations. Today’s complex consequently needs to be understood in layers: original construction, later occupation and subsequent rehabilitation.

When comparing forts and watchtowers across the UAE, begin with three questions: what needed protection, who occupied the building, and which parts belong to which period? A tower’s shape alone cannot answer them.

Oasis architecture and the UNESCO distinction

Al Ain’s buildings belong to a wider landscape of cultivation and water management. The أفلاج, aflaj, are irrigation systems; the singular is falaj. UNESCO’s account connects these systems with settlements, agriculture and the long development of oasis life. Houses, defensive structures and water infrastructure belong together, rather than being viewed as isolated monuments.

The Cultural Sites of Al Ain (Hafit, Hili, Bidaa Bint Saud and Oases Areas) were inscribed on the UNESCO World Heritage List in 2011. This is a defined, multi-part property, not a blanket listing for all traditional architecture in the UAE. Its significance includes archaeological remains, irrigation and earthen buildings. Use the guide to Al Ain’s oases and UNESCO sites to distinguish the different components.

Conservation starts with understanding the building

Record before repairing

Conservation begins with evidence: recording materials, mapping damage and understanding alterations. Stone-conservation practice includes investigating mortars, moisture and structural behaviour before choosing treatments. A repair that looks convincing is not necessarily compatible with the wall underneath.

At Qasr Al Hosn, investigations linked modern render and introduced air conditioning with moisture trapped against historic coral masonry. The conservation project addressed that interaction. It shows how an apparently protective modern layer can create problems for older construction.

Repair the causes, not only the appearance

Research on Al Ain’s mud-brick buildings describes repairs to eroded walls, cracks, roofs and wall tops. These tasks are connected: repairing a damaged surface without addressing the source of deterioration leaves the building vulnerable. Conserving earth requires attention to the whole structure rather than a fresh coat that conceals the damage.

Material analysis and carefully selected treatments are equally important for stone. Mortar repairs, moisture control and structural stabilisation are specialist decisions, not interchangeable finishing options.

How to look closely on a visit

Use these questions to move beyond the façade:

For deeper study, the reading list of books, archives and digital libraries is a useful next step. Compare a measured drawing or an early photograph with the building: the most revealing detail may be a blocked opening, a changed roofline or a room added after the original construction.

Questions

Are arish and barasti the same thing?
Both terms are commonly used for palm-frond buildings. Construction varied: different panel arrangements provided ventilation, shade or greater enclosure.
Did wind towers cool an entire house?
A barjeel typically served the room beneath it and worked within the building’s wider ventilation arrangement. Its effect depended on airflow and the surrounding design, rather than providing uniform, mechanically controlled cooling.
Where can I compare coastal and inland architecture?
Al Fahidi in Dubai illustrates coastal masonry and wind-tower construction, while Al Jahili in Al Ain is a substantial example of inland mud-brick fort architecture. Check the relevant official venue information before travelling.
Does restoration mean everything visible is original?
No. Historic buildings may combine surviving fabric, later alterations and conservation repairs; Al Jahili, for example, underwent both military expansion and later rehabilitation. Interpretation panels can help distinguish these phases.
