|  The first certain news relating to 
                a castle built on the same place of the palace can be dated back 
                to the 1100, when Zagarolo was destroyed by the soldiers of Pasquale 
                II (1099-1118), to suppress the rebellion of Pietro Colonna. The 
                powerful family possessed again this castle, but the struggles 
                with the Papacy were not ended, and the fortress was destroyed 
                twice: one in 1297 from Boniface VIII (1294-1303) and in 1400 
                during the struggle against Boniface IX (1389-1404). In 1503, 
                thanks to Giulio della Rovere (1503-1513), the Colonna possessed 
                again the town; in 1586 Sisto V (1585-1590) was hosted in Zagarolo.
                 In this period the palace was restored and were added the two 
                  wings towering over the square. One of the guests of Marzio 
                  Colonna was the painter Caravaggio in 1606. In 1622 the town 
                  was bought by the Cardinal Ludovico Ludovisi, who enriched the 
                  palace with a picture gallery. In 1670 the new owner was G. 
                  Battista Rospigliosi. This family transformed Zagarolo in an 
                  important international centre, hosting nobles and artists, 
                  among which Vittorio Alfieri. During the 19th century began 
                  the decline of the palace, and during the second world war it 
                  was transformed in a military hospital and in a refuge for the 
                  evacuees.  
                Many rooms at the ground floor and at the main floor are still 
                  characterized by the original decorations, frescoes representing 
                  allegoric figures, important events of the Lepanto's Battle, 
                  landscapes and coats of arms. 
                At present the palace is owned by the Town Hall and is being 
                  restored. The rear door is very interesting: it was built by 
                  Marzio Colonna in 1600 to celebrate Lepanto's Battle victory. 
                  It is decorated with roman friezes and marble busts projecting 
                  on the local stone.
