The medieval old-town, Terra Murata, rises on the tuff-stone mountain of Procida island. The name come from the ancient usage to share the land according to the way of the employment of it: land for wheat, land for pasture, land for vineyard and farming, and Terra Casata, where are set the residences. At the beginning the land wasn’t surrounded by protection walls, but in XVI century, the Cardinal Innico d’Avalos of Aragon ordered their erection and the land was called “murata”. The first settlement, typically medieval, presented small adjacent buildings, set around the pre-existing patronal Villa and the Abbey, in order to defence the housing complex. The habitation entrances were set inside and the small windows outside. After the construction of the wall, in XVI century, the building trade changed; the windows became bigger and small balconies were built. The housing scheme also changed through the including of Porta Mezz’Omo and the destruction of the Porta dell’Angelo that was the primal entrance of the village. The new entrance became Porta di Ferro. The regal palace was built in 1563 on the top of the mountain and it has been a jail until 1988.
