Origin and history
The building at 5 rue Émile-Letaillandier in Lannion is an emblematic example of 16th century Breton civil architecture. Its facade, covered with wooden panels, illustrates the traditional constructive techniques of the Costa Rican houses, characteristic of the north coast of Brittany. These wooden elements, often assembled in checker or diamond, served both as ornament and as protection against maritime weather.
A dendrochronological study conducted in 2021 by Valentine Guillevic made it possible to date precisely the implementation of the woods of the house between 1594 and 1652, confirming its Renaissance origin. This type of construction reflects the relative ease of the then Lannonian bourgeois or merchants, linked to port activities and maritime trade. The house was partially protected in 1926, with the inscription of its facades and roofs in the inventory of Historic Monuments.
The historic address of the building has evolved over the centuries: initially located on Rue du Port (central axis of the medieval city), it now bears the name of Émile Letaillandier, a local figure not documented in the available sources. The accuracy of its current location is considered passable (note 5/10), perhaps reflecting urban changes after its construction. No information is available on its contemporary use (visit, accommodation, etc.).
