Cathédrale Saint-Pierre et Saint-Paul de Nantes

It is the cathedral of the Diocese of Nantes, the seat of the Bishop of Nantes.
Its construction is spread over 457 years, from 1434 to 1891, but these delays do not affect the quality or consistency of the Gothic style.
It is classified a historical monument in 1862.
