About Isola Bisentina#
Isola Bisentina is a small lake island in Lake Bolsena, Lazio, Italy, and is the larger of the two principal islands in the lake. It sits within one of Italy’s volcanic lake basins and is part of the local lake landscape.
A compact visit typically includes short walks around wooded areas and viewpoints over the water. The island is reached by private boat or organised boat trips from nearby towns, and visits are usually brief due to the island’s small size.
The island has historically hosted built structures and cultivated areas at various times, reflecting changing ownership and uses through the modern period. Specific buildings and landscape features on the island date from different eras and have been altered over time.
Geographically it lies in the northern part of Lake Bolsena in central Italy, roughly 100 km north of Rome; the nearest lakeside towns are Capodimonte to the north and Bolsena to the west.
- Setting: Located in Italy’s Lazio region on Lake Bolsena, one of the largest volcanic lakes in Europe at roughly 113 km².
