If well implemented, it can considerably contribute to reducing the cooling energy consumption of a building.

The first two photographs here, are likely to have been taken from the same imagecaptured in Apriland show an aerial view of the ruined fort at Helwan, situated to the south-east of Zubara.

Also included are photographs taken from a publication of the Qatar History Committee in My intention here is to show as wide a selection of old photographs as I can find in order to present a rounded picture of the immediate past of Qatar by the addition of what I hope will be an appropriate commentary.

I have come across no other photographs of structures in that area of anything approaching this height. As to what purpose the building had, I am unsure, but there is a suggestion in the two photographs which follow it — and are of the same building, but six years later on, taken in — that it is the remains of the house of a pearl merchant.

Whatever its function, the outside of the building illustrates a relatively defensive attitude in the small apertures some distance from the ground, though there do appear to be semi-circular openings at ground level — either doors or, more probably, windows — and located within an arched wall construction as can be seen in the upper photograph which illustrates its interior.

The walls and arches are of masonry construction and, unusually are dressed in order to provide a degree of accuracy and structural coherence not attainable with the regular hasa construction of most of the traditional buildings in the peninsula.

Note that the wall appears to show springing suggesting that there might have been a domed construction, or at least arches — it was difficult to see from the original photograph if the springers were developed laterally to support domes.
