Bolsena lake

          Lake Bolsena (Italian: Lago di Bolsena) is a crater lake of central Italy, of volcanic origin, which was formed starting 370,000 years ago following the collapse of a caldera of the Vulsini volcanic complex into a deep aquifer.

          The surface area is 113.5 km² (43.8 sq mi), and the maximum depth 151 m (495 ft). It has 2 islands: Bisentina and Martana. With an area of 17 ha (42 acres),
          Bisentina is the largest island, and is accessible via a ferry service from Capodimonte. On the island are groves of evergreen oaks, Italian gardens, and various monuments: the church of Saint James and Saint Christopher with its cupola built by the architect Jacopo Barozzi da Vignola; the Franciscan convent; the Rocchina, a small temple dedicated to Saint Catherine.
           Located opposite the town of Marta, the island of Martana is reputed to have once guarded the relics of Saint Christine to keep them from falling into the hands of the barbarians. Later, it is said that, during the dominion of the Goths, the Gothic queen Amalasuntha was assassinated there. The island is currently private property and no visitors are permitted.
