Few towns in Portugal reveal the Algarve’s medieval past as completely as Silves. Rising above the fertile valley of the River Arade, its massive red sandstone castle dominates the landscape from miles away, recalling a time when this quiet inland town was the political, military and cultural capital of the entire Algarve. Long before the beaches of southern Portugal attracted visitors from around the world, Silves was one of the richest cities on the Iberian Peninsula, renowned for its scholars, poets, merchants and strategic river port.
The origins of Silves date back well before the Middle Ages. The Romans established the settlement of Cilpes, taking advantage of the navigable River Arade, which at the time allowed ships to sail much further inland than today. Following the collapse of the Roman Empire, the Visigoths occupied the town before it entered its golden age under Moorish rule after the eighth century. Known as Xelb, Silves became one of Al-Andalus’ most important cities, protected by formidable walls and surrounded by fertile orchards irrigated through sophisticated Islamic engineering.
The town reached the height of its prosperity during the eleventh and twelfth centuries, when it rivalled cities such as Córdoba and Seville in wealth and learning. Writers, mathematicians, physicians and poets gathered here, while merchants traded cereals, olive oil, almonds, figs, leather and cork through the busy river harbour. At that time the River Arade was deep enough for commercial vessels to reach the city directly, making Silves the principal inland port of the Algarve.
Dominating everything is the magnificent Castle of Silves, regarded as the finest preserved Moorish fortress in Portugal. Built mainly between the eighth and thirteenth centuries using distinctive red sandstone, its powerful walls, eleven towers and enormous cistern demonstrate both the military importance and engineering skill of Islamic Algarve. Walking along the battlements provides spectacular views across the old town, surrounding orange groves and distant Serra de Monchique.
One of the castle’s greatest curiosities lies beneath its courtyards. The enormous medieval cistern, capable of storing thousands of litres of water, ensured that the fortress could withstand lengthy sieges. Another remarkable feature is the deep well traditionally known as the Well of the Dog, reached by a spiral staircase descending into the rock. According to local legend, a faithful dog continued guarding the well after its owner died, giving rise to the name that survives today.
Silves changed dramatically in 1249 when King Afonso III completed the Christian conquest of the Algarve. Although the castle remained strategically important for some time, the gradual silting of the River Arade reduced its commercial significance. As larger ships could no longer reach the city, trade increasingly shifted towards the coast, allowing ports such as Faro to become more influential while Silves slowly returned to the quieter market town it remains today.
Another fascinating curiosity can be found in the cathedral. The Sé de Silves was constructed on the site of the former Great Mosque following the Reconquest, symbolising the profound religious and political transformation of the city. Archaeological discoveries throughout the historic centre continue to uncover Islamic houses, cisterns, streets and everyday objects, illustrating just how advanced medieval Silves had become centuries before much of northern Europe experienced similar urban development.
For motorhome travellers, Silves is one of the easiest historic towns in the Algarve to visit. During our stay, the dedicated motorhome area provided a spacious and well-organised base within comfortable walking distance of the historic centre. The atmosphere remained peaceful throughout the night despite its popularity, while the generous parking spaces easily accommodated larger vehicles. Fresh water and waste disposal facilities made it an excellent place to prepare for the next stage of the journey, and the short walk into the old town avoided the difficulties of driving through Silves’ narrow historic streets. It proved to be one of the most practical and pleasant motorhome stops in the western Algarve, combining convenience with a remarkably quiet setting.
Perhaps the most remarkable aspect of Silves is how completely its medieval identity survives. Unlike many historic towns that have expanded far beyond their ancient walls, Silves still revolves around its castle, cathedral and steep cobbled streets. The red sandstone walls glowing in the evening light, the scent of orange blossom drifting from the surrounding countryside and the quiet atmosphere after day visitors leave combine to create one of the Algarve’s most memorable destinations.
Today, Silves offers something very different from the coastal resorts for which the Algarve is famous. It is a place where Roman merchants, Moorish scholars, medieval kings and modern travellers all form part of the same remarkable story. Exploring its castle, walking its ancient streets and watching the sunset from the battlements provides not only one of the finest historical experiences in southern Portugal, but also a reminder that the Algarve’s greatest treasures are not always found beside the sea.
