The principal square, the place d'Armes, is surrounded by arcaded houses and shaded by trees.
These comprise portions of the church, including the fine west front, arcaded, with three Norman doors and a Perpendicular window, with the chapter-house, cloisters and conventual buildings.
Ornament of the city was the arcaded and roofed bazaar called Chihar Chata, ascribed to Ali Mardan Khan, a noble of the 17th century, who has left behind him many monuments of his munificent public spirit both in Kabul and in Hindustan.
It is a medieval walled town, with an arcaded market-place, a cathedral, the Gothic church of S.
Andrea, founded in 1093, still preserves the lower part of the original arcaded facade in black, white and coloured marble.
