Surrounding the Old Town of Ibiza are colossal stone walls that encompass the Sant Jaume and Sant Pere bastions. These fortifications were constructed during the 16th century to protect against attacks by pirates from Turkey and North Africa. Explore the ancient strongholds to learn about their history and to enjoy exceptional views over the city and the sea.

Enter the Old Town through one of its five entrances and embark on a bastion-to-bastion tour. There are seven in all, and the route is signposted. At Sant Jaume Bastion, browse exhibits that cover military technology from the 16th to the 18th century. See cannons, muskets, cannonballs, swords and armor pieces. Try on a helmet.

Go to the Sant Pere Bastion and walk around the small courtyards where artillery was historically kept. Watch audiovisual presentations that describe the technical challenges that had to be overcome and show how the defensive walls were built. The reproduction of a scaffolding system provides information on the method of construction of the walls.

Spend time at the other bastions that make up the wall. They include Santa Llúcia Bastion, which houses an 18th-century arsenal, and the San Joan Bastion. This is home to two gatehouses, the Hall of Arms and the Contemporary Art Museum of Ibiza. To access the Sant Tecla Bastion, you will need to walk through the Archeological Museum. As you do, pause to browse Roman, medieval, Phoenician and other artifacts that cover thousands of years of history.

The protective walls and bastions are located in the upper part of Ibiza Town. Arrive by bus or taxi or drive. The closest car park is near the entrance to Sant Pere Bastion and requires payment, but free parking facilities are available near Sant Bernat Bastion.

Sant Jaume and Sant Pere bastions are open every day except Mondays. Pay the admission charge that covers both bastions. Ask for the discount for students, children and seniors.
