Abbatiale de Déas (Abbatiale Saint-Philbert-de-Grand-Lieu)

The Abbatiale of Déas, in Saint-Philbert-de-Grand-Lieu, is a Carolingian abbey church presented on its own site as an architectural jewel, with about 1,200 years of history and heavy pillars combining stone and brick. The site offers guided visits, a garden of simples and occasional summer evening visits. Its agenda also includes public concerts, such as a free fado concert by Tânia Raquel Caetano in September 2026 and a concert of veuzes in April 2026, as well as a recorded concert by singer Françoiz Breut.
