Fortaleza de Ferragudo is a historic fortress located in the Algarve region of Portugal. It is situated in the small fishing village of Ferragudo, which is located on the left bank of the Arade River, opposite the city of Portimão.

The fortress was built in the 16th century by King Manuel I of Portugal as part of a defensive system to protect the coast from pirate attacks. Its strategic location allowed it to control the entrance to the Arade River and defend the city of Portimão from enemy ships.

The Fortaleza de Ferragudo has a unique architectural style, with thick walls and small openings for cannons, designed to protect against naval attacks. The fortress was originally built as a military structure, but it has been converted into a cultural center that hosts exhibitions, concerts, and other events.

Visitors can explore the interior of the fortress, which includes a chapel, a courtyard, and a terrace with views of the river and the surrounding area. The fortress is also home to the Centro Interpretativo do Património Islâmico, which showcases the Islamic heritage of the region.

Today, the Fortaleza de Ferragudo is a popular tourist attraction and an important piece of Portugal's cultural heritage. Its picturesque location, historic architecture, and cultural significance make it a must-visit destination for anyone traveling to the Algarve region.
