Walking tours of the city all start in the Old Town, where you can admire the beautifully restored buildings and see landmarks such as the Basilica of Saint Martin, Charlemagne’s Tower, and Saint-Gatien Cathedral. The Old Town is also home to the Compagnonnage Museum and the Museum of Fine Arts, which has a cedar tree allegedly planted by Napoleon Bonaparte in its garden. Place Pumereau—a square surrounded by cafés, restaurants, and boutiques—is a lively destination for people-watching. Visiting Tours is a popular day or multi-day trip from Paris, often combined with the highlights of the Loire Valley.
