Porta Torre, Medieval gate tower in Como, Italy
Porta Torre is a medieval gate tower in Como that rises approximately 40 meters high with massive stone walls and multiple arch openings. The structure features a wider internal arch for city access and external paired arches visible from outside the fortification.
The Roman walls of Como were demolished by Milan at the end of the Ten Years' War in 1127. After allying with Frederick Barbarossa, the city rebuilt its walls with imperial consent from 1154. Around 1192 the podestà Uberto de' Olevano added three towers on the south side; Porta Torre stood in the centre, its foundations consolidated on piles, facing the road to Milan.
Porta Torre was long called Porta di Milano because it faced the road to Milan, and it stood as a symbol of Como's independence after the city allied with Frederick Barbarossa. Its other historic names include Porta delle Meraviglie and Torre di Porta Vittoria.
Visitors can explore both the exterior and interior sides of the tower to see defensive features and architectural details across four levels. It helps to allow time for both perspectives to fully understand the overall structure and its construction approach.
The eight upper arches sit off-axis from the large ground-floor arch because the stair to the upper floors ran alongside them. The paired arches on the city side mark four wooden internal floors, now lost, and left the inner face open to fire from the town if attackers took the tower.
