The narrow ancient streets of the medieval centre are still preserved, as well as the castle, once a possession of the Benedictine Order; it dates from the 11th century. The castle is built at the end of a spur, overlooking Arsoli on one side and extending formal gardens on the other. four frescoed rooms on the piano nobile are flanked by guardrooms hung with arms, armor and family portraits.
This rocca has been in his possession since it was purchased by Fabrizio Massimo in 1574.[3] He commissioned Giacomo Della Porta to remodel the church and commissioned the construction of an aqueduct to supplement inadequate wells, for the abundant springs of Arsoli have been tapped to serve the city of Rome since 600 BC, traditional date of an aqueduct, built, according to tradition, by Ancus Marcius.
^The three hundredth anniversary of the Massimo presence at Arsoli was celebrated with festivities in 1874, according to information provided by Prince Massimo to Tryphosa Bates Batcheller, Italian Castles and Country Seats 1911:442f.
