Siam is the heart of Brest, organised around rue de Siam, the great shopping street that runs down from place de la Liberté, where the town hall stands, to the château and the commercial port. The district owes its name to the embassy of the king of Siam received in Brest in the seventeenth century. Rebuilt after the bombing of 1944 to the regular plan of Jean-Baptiste Mathon, it lines up stone buildings, shops and the tram stop that runs along rue de Siam.
The district concentrates the landmarks of the city: the château of Brest and the Tour Tanguy at the mouth of the Penfeld, place de la Liberté and its fountains, the shopping streets of the centre, and the lower station of the urban cable car that crosses the Penfeld towards the plateau des Capucins. The building stock, uniform and from the reconstruction, mixes high-end apartments and commercial premises in a dense, lively centre.
Sought after for its central position, its shops and its tram links, Siam is the most expensive area in Brest. What is on offer here is mainly apartments, from studios to large flats, popular with working people and investors alike for their location at the heart of the city.
