Forte da Ínsua

Forte da Ínsua is a star-shaped fortress on an island in the Minho River, built for river defense with rooms distributed across multiple levels. The structure includes a chapel and was designed so that every section of the river could be watched from the walls.

The fortress was built in the mid-17th century as a new defensive structure under a Portuguese king's orders. The location had housed a religious community for centuries before, which held control of this strategic river section.

The small church inside shows religious elements with arched ceilings and columned areas that reflect the spiritual past of the place. Visitors can still see today how military defense and religious life existed side by side within these walls.

The site is today open as a guest facility with rooms and dining for visitors, and offers guided tours along the river. Since the fortress sits on an island, visitors should check in advance how to reach it and allow extra time for the journey.

On the island sits a freshwater well located below sea level, a rare feature found in only a handful of places worldwide. This natural occurrence remains a surprising discovery for many visitors who explore the site.
