important role in the local economy. Marketplace A complex array of small storage rooms have been identified as part of the souq (market) of Zubarah. The wide variety of trade objects that have been found in the rooms points towards the area's classification as a place of trade. The souq would have been the centre of the town and of its economy. Various commodities, including ironsmithing, were sold at this souq. Historical architecture Infrastructure The architecture consisted mainly of courtyard houses, a traditional form of Arabic architecture which can be found throughout the Middle East. A series of small rooms were organized around a large central courtyard, where the majority of daily activity took place. Typically, a portico opened out onto the courtyard on the south side, which offered shelter from the sun. The houses of Zubarah were constructed from soft local stone, or from limestone quarried from the northern settlement of Freiha. The stone was then protected by a thick gypsum plaster coating. Features such as doorways and niches were decorated with geometric stucco designs. Housing units were accessible by a doorway and a bent corridor, in order to avert unauthorized viewing into the household, and to prevent sand from blowing into the house. Traces of what seems to be tent placements and/or palm-leaf and palm-matt huts found near the beach may be associated with transient members of the Zubaran society. It is likely that these interim dwellings housed the people who were the primary producers of Zubarah's wealth: the pearl fishers and mariners who harvested the pearl banks each season. The most impressive and colossal of the building complexes measures 110 m by 100 m in size and is commonly referred to as 'the palace'. This structure follows the same form as the domestic architecture seen elsewhere in Zubarah, but on a much larger scale. Nine interconnected compounds, each comprising a courtyard surrounded by a range of rooms, made up the interior of this structure. Plaster stucco decoration was used to embellish internal entrances and rooms. The discovery of internal staircases indicates that the compounds were multi-storeyed. The nine compounds of the complex were enclosed by a high circuit wall with circular towers at the four corners, each of which were capable of supporting a small cannon. The size and visual dominance of the palatial compound suggests that it was occupied by a family of wealthy and powerful
