6 castles to visit in the Algarve

Castle of Silves

The Castle of Silves is classified as a National Monument and is the largest and most important castle in the Algarve. Built by the Arabs in the 11th century, it reflects the splendour of Islamic civilisation at the time and the region's significance. Situated at the highest point of Silves, the castle offers sweeping views of the Arade Valley and the town. It is regarded as the best-preserved Moorish castle in the country. Visitors can walk through its wide sandstone walls and immerse themselves in the castle’s rich history.

Castle of Castro Marim

Built in the 13th century during the reign of King D. Dinis, the Castle of Castro Marim is one of the most significant medieval monuments in the Algarve. Located within the Reserva Natural de Sapal de Castro Marim and Vila Real de Santo António, it provides breathtaking panoramic views over the river, marshlands, mountains, salt pans, and the coastline. The castle is also home to an annual medieval fair, which attracts visitors from all over.

Castle of Lagos

The Castle of Lagos has origins dating back to Roman times, although it was during the Muslim conquest that the fortifications were enlarged and strengthened. It served as the House of the Governors of the Algarve until the great earthquake of 1755, which was followed by a devastating tsunami. The castle was rebuilt after the disaster and later recognised as a National Monument. Today, visitors can explore its historic walls and learn about the important role it played in the region’s past.

Castle of Paderne

Paderne Castle, located in the municipality of Albufeira, is one of the seven castles represented on the flag of Portugal. Built in the latter half of the 12th century during the Arab occupation, it is a prime example of Muslim military architecture in the Iberian Peninsula. The castle, which has been a National Monument since 1971, stands as a significant testament to the Almohad period and the final phase of Muslim rule in the Iberian Peninsula.

Castle of Loule

The origin of the Castle of Loulé dates back to the medieval city of Al'-Ulya, founded by the Muslims in the 8th century. Following its reconquest by D. Afonso III in 1249, the castle was rebuilt, and Loulé became part of the Portuguese crown. It grew into one of the Algarve's main mercantile centres during the Middle Ages. Today, the castle is an iconic landmark, showcasing the region’s rich cultural and architectural heritage.

Fort of São João de Arade

Located in Ferragudo, the Fort of São João de Arade is perched on two beaches: Angrinha Beach and Grande Beach. It dominates the landscape at the mouth of the Arade River. Built on solid rock, it is one of the few castles that was not destroyed during the earthquake of 1755. The fort is well preserved, with a large walled garden and several battlements. Its strategic location and beautiful surroundings make it a must-visit for anyone interested in the Algarve's military history.
