Beautiful old town with many half-timbered houses. The cathedral is particularly impressive. We were there on Wednesday. The weekly market is a shadow of its former self. 10 years ago it was much busier.

The Nantouar Lighthouse is a beautiful and picturesque lighthouse located in the commune of Louannec in the Brittany region of France. Built in 1858, the 73-foot-tall lighthouse is a French national monument. Its lighthouse keepers used it to guide ships to safety, away from dangerous rocks and reefs. From the top of the lighthouse, visitors can enjoy breathtaking views of the surrounding landscape and the bay. The nearby harbor is a great place to enjoy a variety of water sports or simply relax by the sea. Tourists can explore the many surrounding islands and discover a unique habitat for wildlife. The area's main beach, located next to the lighthouse, is a great place for a stroll and to breathe in the salty sea air. Not far away, you can visit the fascinating Ploumanac'h National Nature Reserve, known for its dramatic marine scenery and amazing seabirds. For a truly immersive experience, take part in The Great Route, a 12-km circular hiking trail. The spectacular coastal path allows you to explore the local coastline and offers ample opportunity to enjoy the breathtaking scenery. Although not necessarily the most active tourist destination, the Phare de Nantouar is still well worth a visit for its beauty and history.

The chapel of Saint Uzec was erected in the 14th century, on the boundary of parishes between Pleumeur-Bodou and Trébeurden: the old path, with an east/west axis, still exists, and the Calvary would be the exact boundary between the two parishes. Located on an imposing rock, subsequently largely carved out to provide passage for the road, it faces the menhir of Saint Uzec, visible on the opposite side of the valley. It is adjoined, as is often the case, by a fountain recalling old rites of water worship. It was partially destroyed by lightning in 1974, and gradually restored thereafter, at the initiative of the residents of the neighborhood and the municipality.
