La Sagra di San Giovanni is the oldest event in Lake Como, known for its tradition, art, faith, and folklore. It finds its enchanting setting on Isola Comacina, making it a unique and remarkable occasion. The festival, featuring spectacular fireworks and a music show — the most renowned fireworks display in Lake Como — as well as the symbolic burning of Isola Comacina, commemorates the glorious past of the Tremezzina area and Lombardy. It also marks the beginning of the tourist season in the Centro Lario region. The Festival of San Giovanni (Sagra di San Giovanni) program includes the grand fireworks display, a solemn procession on the island with costumed participants, a regatta featuring the historic “Lucie” boats of Lake Como, and gastronomic evenings.
During the War of the Ten Years, which erupted in 1118 due to the rivalry between Como and Milan for control over major trade routes and Alpine passes, Isola Comacina and many other municipalities in the Lake Como region sided with Milan. Despite suffering two bitter defeats against the Milanese duchy, Como was finally conquered in 1127. The devastating loss prompted the people of Como to ally with Frederick Barbarossa during his anti-Milan expedition in Italy. Isola Comacina quickly fell under the control of Como and was invaded, set ablaze, and razed to the ground in 1169. The island was never repopulated, and the few survivors relocated to Varenna, which became known as “insula Nova” (New Island) after that.
The Festival of San Giovanni (Sagra di San Giovanni) is a testament to the resilience and cultural heritage of the region. The grand fireworks display, synchronized with captivating music, illuminates the night sky of Lake Como, creating a mesmerizing spectacle that captivates visitors.
