The renewal of the Olival hill was greatly favoured by the development of new urban roads, whose paths were lead to the doors of the Gothic wall (the Carros door on the foot and the Olival door on the plateau), surrounding the core of the Jewish Quarter. This very disposition was determined by the difficult conditions of the site and explains the outline of the Taipas and Dr. Barbosa de Castro streets. Nonetheless, this urban development registered periods of inactivity, due to the isolation imposed by such conditions.
