From the Neolithic to WW2: two outstanding monuments
They are not open all year long, so make sure you won’t miss the dates in order to visit two monuments separated by approximately 6,000 years: the neolithic barrow of Dissignac (Tumulus de Dissignac) and the submarine base in the harbour of Saint-Nazaire.
The submarine base
With its 301 metre-long façade, the submarine base, built by the German army during World War 2, still dominates the harbour site today. The guided tour tells its history and how, in the 1990’s, the City of Saint-Nazaire developed Ville-Port, a town planning project which turned the former fortress into a link between the town and its harbour.
From 10 July to 28 August, every Monday at 16:30. The guided tours last 1 hour and 10 minutes, commentaries are in French. They leave from the central ticket office in the submarine base, Boulevard de la Légion d’Honneur.
A 6,000-year old burial chamber
The barrow, or tumulus, is a megalithic tomb with two burial chambers, in the Dissignac area on the outskirts of Saint-Nazaire. It was built approximately 6,000 years ago and is considered one of the most remarkable prehistoric monuments of the whole region. An engraved stone slab with mysterious symbols is hidden within one of the burial chambers.
From 9 July to 3 September, every day except Saturday and Monday, 10:30 to 13:00 and 14:30 to 19:00. Last entry at 12 o’clock and 18:00. The guided tours last 45 minutes, commentaries are in French. The barrow is situated on the outskirts of Saint-Nazaire, route de Dissignac.
