Sagres Fortress is the prime historical landmark in Sagres. The fort is now a tourist attraction. It only costs a few Euros to enter, which is a bargain compared to other sites in the country. Once you are on the grounds, you can walk around freely. As you walk there are sites on the property that you can stop and read about. In the middle of the grounds is the main ammo battery storage. You can see the rocks that were used to protect the ammo from the elements. Since this is on the shore, you have to make sure the ammo is safe and secure.
