Origin and history

The house in Dinan, dated from the 12th and 13th centuries, is part of an ancient architectural complex of the town of Treméreuc, organized around the parish church of St. Lawrence, built in the 12th century. The first constructions, in granite and granulite bellows, form characteristic alignments along streets such as the Church Street or the Butte Square. These houses, often houses or former manor houses such as the Hervias, reflect a dense medieval occupation, confirmed by the Napoleonic cadastres.

The town gradually developed around the church, with a majority of houses dating from the 17th, 18th and 19th centuries. Urbanization accelerated in the 19th century thanks to the National Highway 166 (1824) and a rail stop, attracting a majority of the population of sailors. This context influenced local architecture, with "engineer" style houses (symmetry, hip roofs) such as the one built in 1864 by Jean-Marie Lemoine, captain of marine, 11 rue de Bel Air.

In the 20th century, industrialization and architectural movements introduced new styles, such as neo-breton in the 1950s, especially near road and rail routes. Despite these developments, the village has retained some of its authenticity, with a medieval urban fabric partially preserved. However, recent urbanization has altered this heritage, with the addition of subdivisions and individual houses between the historic centre and the peripheries.

The house of Dinan, classified as a Historic Monument in 1961 for its facades and roofs, illustrates this historical stratification. Its alignment with other ancient buildings, such as those on the Apport Street or the Clock, bears witness to the medieval organization of the village, centered on the church and the craft activities (forges, outbuildings). The 17th century interior chimney, visible in some houses, recalls the subsequent transformations of these buildings.
