The vast, beautiful Námesti Otakar II square is the site of stately Renaissance, Gothic and Baroque buildings, including the beautiful 1727 town hall. Buses and trolleys link areas, and cycling paths run through the city.

Located on the Bay of Biscay, La Rochelle’s history mostly involved the sea; today it has a large pleasure-boat marina. Thus its heart is the picturesque "Vieux Port" ("Old Harbor").
