If you are an admirer of Victor Hugo, the famous French writer and poet, you may want to visit the Victor Hugo Museum. This museum is located in a 19th century mansion which belonged to the family of Hugo's son-in-law, Charles Vacquerie, who married his daughter Léopoldine. Unfortunately, both drowned in the Seine shortly after their marriage, a tragedy which deeply affected Hugo and inspired some of his most moving poems. The museum displays personal items, letters, photographs and first editions of Hugo and his family, as well as the furniture and decoration of the house. You can also enjoy the beautiful view of the Seine from the garden and the terrace. The museum is open every day except Tuesday and Sunday morning, and the entrance price is €5 for adults and €3 for reduced rates. You can also book a guided tour for groups of 15 people or more.
