Contrary to popular belief, you can visit excellent museums in Paris without spending a cent. The City of Paris and several institutions offer free, permanent access to their main collections, only temporary exhibitions usually charge admission.
The Musée Carnavalet
Devoted to the history of Paris from its origins to today, this museum housed in two Marais mansions reopened after renovation with a remarkably clear layout. The recreated apartments and old Parisian shop signs are a real treat, even for visitors with little background in the city's history.
The Petit Palais
Built for the 1900 Universal Exhibition, this palace houses the City of Paris's fine art collections, from antiquity to the early twentieth century. The inner courtyard with its garden and mosaic is one of the most relaxing spots near the Champs-Élysées.
The Victor Hugo House
The writer lived for sixteen years in this apartment on Place des Vosges, now turned into a museum tracing his life and work through furniture, manuscripts and drawings. The visit naturally ends with a break on one of the most beautiful squares in Paris.
Tips
Permanent collections at City of Paris museums are free year-round, with no age or ID requirement. Only temporary exhibitions charge admission, so always check which is which before queuing at the ticket desk.
