Ciudad de Ibiza - Upper Town

Above the lower town rise the massive walls of the fortress, built on the remains of the Arab walls between 1554 and 1585 by an Italian architect, Calvi, at the behest of the Emperor Charles V. The circuit of walls, with seven corner bastions and three gates, encloses the upper town (Ibizan D'Alt Vila) with its winding stepped lanes and old patrician houses.
