Located in the centre of Saint-Germain-en-Laye, a 17th-century house is currently home to the town's tourism office. This building is also the house that saw the birth of one of the greatest French composers, Claude Debussy.

Saint-Germain-en-Laye has devoted a museum to him, on the first floor of the house where he was born. This area is accessed via a lavish wooden staircase. It brings together objects and photographs belonging to the composer, and evokes the great passions of his life: poetry, literature, and painting. The museum is listed as a "Maison des illlustres" ("House of the Illustrious") by the Ministry of Culture. The city's tourism office is located on the ground floor of the Claude Debussy house. A visit to the museum thus also gives you a chance to learn about other things to see in Saint-Germain-en-Laye, starting with the National Museum of Archaeology.
