This collection brings together buildings that demonstrate seven centuries of Breton architecture, from the Middle Ages to the modern era. In Brittany, especially in Finistère and its surroundings, these constructions reflect the evolution of techniques and architectural tastes over time. Romanesque churches like the Priory of Locmaria in Quimper, founded in the 11th century by Benedictine monks, Gothic structures such as the Saint-Corentin Cathedral with its two 75-meter towers are present, as well as Renaissance homes like the Kerazan Manor in Loctudy, which retains its original decor. Local materials, notably granite and slate, characterize these buildings and give them a strong regional identity. Some buildings now house museums, such as the former Episcopal Palace of Quimper, which hosts collections from the Breton Departmental Museum, or Kerazan Manor with its Breton artworks. Other sites combine architecture and gardens, like the Lanniron Castle with its 17th-century French-style gardens or Trévarez Castle surrounded by wooded parks. These sites enable visitors to understand Brittany’s architectural history and offer a journey through the centuries.
