Castel San Pietro is a medieval fortress located in the city of Verona, Italy. The castle was built in the 10th century and was originally used as a watchtower to protect the city from invaders. Over time, it was expanded and fortified, and it played an important role in the defense of Verona during several conflicts.

The castle was destroyed and rebuilt several times throughout history. In the 19th century, it was extensively restored and renovated in a neo-gothic style. The current structure features crenelated walls, a central tower, and a large courtyard.

Today, Castel San Pietro is open to visitors, who can explore the castle's ramparts, towers, and underground tunnels. The castle also houses a museum of weapons and armor, which features a collection of medieval and Renaissance-era artifacts.

In addition to its historical significance, Castel San Pietro is also known for its stunning panoramic views of Verona and the surrounding countryside. Visitors can climb to the top of the castle's tower for a breathtaking view of the city and its landmarks.
