The fortress was originally built by the Monaldeschi family, who dominated the political scene of Orvieto in the Middle Ages.
The ground floor of the castle houses a display of remains from the 'Villanovan' culture, specifically from the site of Gran Carro.
The building was constructed as a defensive bastion to secure the Orvieto border against potential invasions from the north.
The basalt used in the walls is a direct reference to the Vulsini volcanic complex that formed Lake Bolsena.
Archaeological findings within the museum include items recovered from underwater explorations of the lake's prehistoric submerged villages.
Rocca Monaldeschi della Cervara is a 13th-century medieval fortress situated at the highest point of the historic town of Bolsena. The structure features a distinctive triangular plan with four corner towers, characteristic of the defensive architecture commissioned by the Orvieto government. It currently serves as the Territorial Museum of Lake Bolsena, housing exhibits detailing the geological and human history of the volcanic lake basin. The museum displays artifacts ranging from prehistoric pile dwellings to Etruscan, Roman, and medieval periods. Visitors can access the tower walkways for elevated views over the Bolsena caldera and the surrounding hills. The walls were constructed using local volcanic basalt, reflecting the regional geological heritage.
