Most of the main attractions of Zagarolo are in the historical town centre, concentrated around the narrow long main street (Via Antonio Fabrini and then Corso Vittorio Emanuele).
The Palace The
Palazzo Rospigliosi, in the city centre, occupies the site of an ancient medieval castle, which is first referenced to when Pope
Paschal II destroyed Zagarolo in the early 12th century after the rebellion of the
Colonna family, of which the palace was one of the strongholds. For many centuries it remained under the Colonna influence, and was besieged and destroyed several times due to the rivalry between the papacy and the Colonna family. In the 16th century, the Colonnas and the papacy started having peaceful relations, and Zagarolo became a
duchy, hence the Palace became known as
Palazzo Ducale. The palace came to be used as a residence and two additional major wings were built towards the piazza, frescoes were added and a
hanging garden was built. It was in this Palace that in 1591 a commission of eight cardinals met to revise the Bible for a printed edition, among them cardinal
Marcantonio Colonna and
Saint Robert Bellarmine. The building is characterized by frescoes painted by mannerist artists of the 16th century, attributed to Dutch painters, to
Antonio Tempesta, and to the Zuccaris (
Taddeo Zuccari and
Federico Zuccari). Here in 1606
Caravaggio created masterpieces for the
Colonna family, in exchange for refuge on his journey to
Naples, between Zagarolo and
Paliano he executed the
Supper at Emmaus,
Mary Magdalen in Ecstasy and perhaps
Saint Francis in Prayer. The Palace also saw the of
Carlo Maratta and of
Ludovico Gimignani, the latter dying there in 1697. In 1668, when the
Rospigliosi acquired the duchy of Zagarolo, the Palace became their property, and was later in possession of the
Pallavicini family, until it was sold to the
comune in 1979. During
World War II the palace was transformed into a German military hospital. Today the local library and Toy Museum are housed in the Palace, and it is used for conventions, exhibitions and other cultural events. Outside the town centre is the
Tondo (as it is called by the local population), located at the hill called the
Colle del Pero. It is a rare example of an ancient
Roman Ludus dated to the 1st century AD, a sort of little
amphitheatre used as a gym or training ground for gladiators (see
List of Roman amphitheatres). ==Geography==
