Fort of Milreu

The Fort of Milreu is a coastal fortification with a rectangular layout, two cylindrical watchtowers, and several cannon positions oriented toward the Atlantic. The structure with its terrace roof and sturdy walls sits on a promontory along the shoreline.

The fortification was built between 1670 and 1675 to protect the Portuguese coast following a conflict with Spain. The structure arose during a period when such defenses were urgently needed along the Atlantic shoreline.

The fort reflects how the Portuguese designed their coastal defenses, with vaulted passages and a central stronghold that remain visible today. These architectural choices show how defensive structures were built to withstand attacks from the sea.

The fort sits about three kilometers north of Ericeira town center and can be reached via the coastal road and walking paths. The route follows the shoreline, so sturdy footwear is advisable.

The fort's garrison was remarkably small, consisting of only about a dozen personnel who managed all defenses. This tiny crew had to operate all the cannon equipment and maintain watch over the fortification.
