Origin and history

The house at 3 rue du Commerce in Landerneau, built in the 3rd quarter of the 17th century (1667), is an emblematic example of bourgeois architecture of this time. It was originally part of a larger complex including two other adjoining buildings, probably warehouses, organized around an inner courtyard. These buildings communicated with the house through today's condemned passages. The rectangular building is distinguished by its eastern facade of Logonna's cut stone, its modillon cornice, and its curved pediment windows decorated with fire pots. A staircase turret with a rump roof completes the whole.

The house was built in 1667 by Arnaud Duthoya, the first wine merchant in the Bordeaux region established in Landerneau in 1660. Designed as a real mansion, it reflects the prosperity of the Landernean bourgeoisie of the time, comparable to the house of the Senate (1664) located in Place du Général de Gaulle. Its interior, although without original partitioning, retains a screw staircase, chimneys and a latrines system in corbellation on the rear façade. The building, fully classified in 2019, now belongs to the municipality.

The location of the house, close to the port, highlights its link with the maritime commercial activities that made Landerneau's wealth in the seventeenth century. Its architecture, combining functionality (warehouses, interior access) and prestige (size stones, ornaments), illustrates the high social status of its sponsor. The Duthoya house and the house on the senate floor thus testify to the economic and urban development of the city during this period, marked by the influence of local traders and elites.
