To assert their success and escape the suffocating world of the city while remaining close to the port, this new merchant aristocracy began to build a haven of peace with superb residences with sober, symmetrical and elegant architecture. In barely a century, nearly 300 such residences were built within a 15-kilometre radius around the historic centre ofSaint-Malo.
All are built with granite from Chaussey, a Breton island off the coast of Granville. The high roofs, gabled chimneys and aligned openings give these buildings an austere appearance, largely offset by the impressive wealth of furniture and interiors where treasures and travel souvenirs accumulate filled with art and history.
