During this event many European and Italian lakes participate in "Bontà lago" (a street market where every lake sells its local products and publicizes its area with some brochures).
Built in the 11th century, it was burnt by Federico Barbarossa and it was restored only in 1611. It now holds a museum, a library and a big convention hall where are organized many concerts and convention during the year.
Composed of two rooms, it contains many Italian Army uniforms used during the First and the Second World Wars.
Santuario della Madonna della Neve
In front of the church there is a church yard with old plane trees. The facade is in Baroque style and in the building there are some frescos by Pietro Brigoli.
It is said to have the first monument ever built to Giuseppe Garibaldi without a horse. Inside, there is also Vantini Palace, the town hall.
It was built probably in the fifth century on the ruins of a previous temple, by St. Vigilio, Brescia's bishop and Iseo's patron saint. The facade is in a Romanesque style with a central bell tower. The most famous painting in the building is St. Michael archangel by the famous Italian painter Francesco Hayez.
Chiesa di San Silvestro o dei Disciplini
It was built between the 13th and the 14th century. It contains some frescos including a Danse Macabre. Now the church is in very bad condition and always closed, but Iseo's FAI delegation (FAI is Italian National Trust) is planning to restore it.
