The palace of King Enzo is located in the center of Bologna, on Piazza Maggiore. The palace was built in 1245 and was originally called the New Palace. At the Battle of Fossalt (1249) the army of Bologna not only won the battle, but also captured the King of Sardinia Enzo, son of Emperor Frederick II. For 23 years, until his death, Enzo was a prisoner in the New Palace. The palace became known as the Enzo Palace. Many legends are associated with King Enzo's imprisonment. It is said that Frederick II was willing to pay a huge ransom for his son, which could build new walls around the city, but Bologna refused to ransom.→
