This is an ancient signal tower dating back to the 12th century. The structure was part of the defensive system of Comacina Island. After the island's destruction by the people of Como (1169), it remained abandoned for centuries. https://fondoambiente.it/luoghi/torre-del-soccorso-detta-del-barbarossa-84041?ldc

At the end of the beach promenade there is "suddenly" a huge building: Villa Olmo. Imposing park with a panoramic view of Como. The bike has to be pushed.

Villa Olmo is a perfect example of Italian neoclassical style. Its elegance and charm didn’t go unnoticed by Napoleon Bonaparte and Giuseppe Garibaldi, who were two of the most notable guests of the villa. The villa began restoration work in early 2024, so its interior will not be open to visitors for about a couple of years. The gardens that surround it are open all throughout the year.

Ruins of a small cave castle, clearly visible and with exposed access in the rock walls north of Mendrisio. A straight, three-story wall closes the natural cave. The main openings and probably the namesake are a high entrance and two windows. There is a cast iron window above the climb. Several embrasures and light hatches have been preserved. According to architectural criteria, the castle dates back to the 15th century. It probably served as a defensive refuge for a local leadership group. The Tanùn (Tanone), another cave on the ascent, which is closed off with a low wall, was probably related to Tri Böcc. An at least indirect connection is conceivable with the grotto hermitage of San Nicolao, which, according to tradition, was built by Loterio Rusca in 1413 in a higher rock echelon.

Property of the Italian Environment Fund. The Torre del Soccorso stands with its massive quadrangular mass in Moltrasio stone, easily recognizable among the vegetation that covers Mount Gravona close to the Comacina Island. The construction dominates the panorama of the lake since its construction, which took place between the twelfth and thirteenth centuries, as part of a larger fortified system, which included the castle of Isola Comacina and the defensive structures of Sala, Lezzeno and Cavagnola. Check the opening periods of the property on the FAI website. From the tower, a sheer view of Tremezzina and Comacina Island
