Porta dei Vacca (o di S.Fede)

In 1155 the defensive wall was extended to north-west to include also the new settlements out of the walls. The walls culminated on the top of St. Andrew hill, with Porta Soprana. The new walls greatly expanded the area contained in it, compared to the previous one. The construction of the walls dragged until 1163: in that year, due to the international political situation, and particularly the relations with emperor Frederick Barbarossa led to an acceleration of work, as Caffaro vouched for, and in 53 days the works were completed, thanks to the effort of the entire population. The 3 main gates had a monumental look, with high semicircular towers. 2 of them survive nowadays, “Porta Soprana”
