The house-tower in Via SS. Quattro

It is an important model of a civil fortified building in Terracina (Italy): it is located at the cross-roads of three important road-axes and so, thanks to its position, its triangular plan, its building technique, its stately construction and its narrow loop-holes, it was, at the same time, a remarkable place of protection and attack inside the medieval town. The house was bought in 1283 by Gregorius de Acso according to an inscription affixed to the front; however, it must have been built a century before. Source: Objaverse 1.0 / Sketchfab
