crossroads

It has its towers arranged in the shape of a theatre, with thoroughfares leading between them now the crossroads of the lower towers are visible but those of the upper towers are more frequented.

There are steps too which lead up to the crossroads, and some people are always going up, and others down and they keep as far apart from each other as possible on the road because of those who are bound by the rules of purity, lest they should touch anything which is unlawful.
