Well, to explain it better I've copied from the internet
Desenzano : San Martino della Battaglia Monoument
The monument, which is about 5 km from the town center, was built in memory of the bloody battle between the French-Piedmont and Austrian troops on June 24, 1859. There is an ossuary chapel with over a thousand skulls and bones of the 2,619 war victims, a museum with documents and relics from the Italian Risorgimento period and the Second War of Independence, and a tower almost 65 meters tall. Topped with a panoramic terrace, the tower was inaugurated in 1893 and dedicated to King Vittorio Emanuele II. The top can be reached by a ramp about 500 m. long. Opening onto the ramp are two galleries and seven frescoed rooms decorated with Risorgimento motifs.
A really interesting place to visit, lots of history and the restaurant near the tower does some fantastic food
