The Basilica de Santa Maria del Mar is one of Barcelona’s most stunning churches and a prime example of Catalan Gothic architecture. Its design showcases a cleaner, more restrained style compared to the elaborate ornamentation typically associated with Gothic structures. Construction began in 1329 and was completed in 1383 — an impressive feat for such a monumental project. Inside, the basilica feels remarkably spacious and airy, with its three naves of equal height supported by towering, slender pillars. The sparse decoration of the chapels enhances this sense of openness. Natural light filters through the magnificent rose window on the main façade and the vibrant stained glass windows, bathing the interior in a serene glow.

The Rio Fortress is a 15th-century Ottoman castle built on the tip of a narrow peninsula, strategically positioned to control the entrance to the Gulf of Corinth. It sits directly next to the modern Rio–Antirrio Bridge. You can explore its triangular layout, stone walls and seawater moat, which offer panoramic views of the strait. At either side of the fortress you'll find narrow pebbly beaches, known as East Beach and West Beach of the Castle, providing a quick dip in the clear waters with a historic backdrop and an unparalleled view of the bridge.

Originally built in the 13th century and restored several times throughout the years, Borj El Kebir is an ancient castle overlooking the Houmt Souk region. It is the largest and best-preserved local castle. On a sunny day, you can take a hike up the hill and enjoy a great view of the harbour.
