Walls in traditional Palestinian houses are constructed with far more tricks and secrets than expected.
This door leading to the roof of the Lama House in Bethlehem has an arched lintel on the inside, and a straight one outside, while it is one undivided wall apart from the arch itself.
The arched lintel is designed to absorb the pressure of the roof, while door frames cannot be arched, the door would not open. Instead of choosing one of the possibilities, they are used at the same time.
Additionally, the stones visible in the outside wall are worked neatly, together with the plaster closing off the surface with no gap, while on the inside, the stones are put into shape only roughly. This might be a measure to save work expenses, since the inside walls are usually fettled.
