The Roshan is an
important and inevitable element in Jeddah’s Old City architecture.
It has esthetical and functional benefits suiting the environmental
and social setting; it gives shade to the road beneath, where people
seek to run away from the sun’s heat, and it gives privacy to the
people living inside and looking upon the road through it.
The Roshan is not
just a complicated carved wood work, it has also environmental
advantages. By opening a lower apertures (according to the direction
of air) the cool air gets in where the hot air goes out through an
upper round aperture; keeping the room well aired and shaded.
