After that the city walls were built and the dangers reduced, they changed the needs of the population and consequently also the houses' peculiarities. They enriched outer facades with larger openings (windows, balconies, loggia) which lessened the closed and defensive character shown by the unbroken line of houses before the town rearrangement. The houses' entries on the internal courtyard of the Casata became less practical, because people were obliged to make long rounds to reach their home, so many dwellers preferred to excavate staircases into the rocks under the houses and built new entrances on the Army Square, with the characteristic portals carved in the tufa.

One of the most interesting architectural episodes in Terra Murata is the House of Belvedere, typical example of the Procida building manner, so that it has been saved from demolition done in the Fifties because of the landslides of the cliff. On the ground floor, which is marked by irregular arches supporting part of the upper floor, there are the rooms designed for community use as workshop or storage. An external stairway rises to the upper floors where are located the private rooms. The first flight of the stairway is covered; the following is at open air. The narrow and covered entrance allowed the owners to have a better control over people who came, avoiding sudden entries by unwelcome guests. Internal rooms follow each other lengthwise, since against blind lateral sides they were leant the adjacent houses.
