There are indications of a Roman settlement. The first written document mentioning "Insulae curtis" dates from 905, when the island was listed among the properties of themonastery of S. Salvatore inBrescia. The familyOldofredi, rulers ofIseo, built on the island two strongholds in the 11th-12th centuries. Members of the powerfulVisconti family came here to hunt in 1400. In 1497Francesco Sforza, duke of Milan, gave the islanders some fishing rights and reduced the taxes. In the same year,Caterina Cornaro, queen ofCyprus, resided a while on the island. During the 19th century the main industry on the island was the construction of boats and the manufacturing of fishing nets.
Peschiera Maraglio and Siviano (the municipal seat)[4] merged in 1929 to create the actualcomune.
The single-nave church of San Michele in Peschiera Maraglio was consecrated in 1648. This baroque church is notable for the many frescoes on the walls and on the ceiling and for its wooden carvings.
