The Château de Dinan is a 14th-century medieval castle located in the heart of the city. It served as a defensive fortification and residence of local nobles. Part of the city walls, the castle features an imposing round tower, battlements, and loopholes. Today, it is a museum and offers panoramic views of the city and the Rance River.

The Porte Saint-Louis is a historic city gate, built in 1620, and one of the main entrances to the fortified old town. It is part of the medieval city walls, which were built and reinforced in the 11th and 14th centuries. Its architecture features an arch and, formerly, a drawbridge. Today, the gate has been restored and is still open to traffic.

The abbey church and cloister are definitely worth a visit.

The viaduct spans the valley spectacularly, and it's particularly beautiful from the harbor.
