There are a lot of great attractions and museums in Lille, and if you have time you should try to see them all. If you walk by the old part of the city you can see the Old Stock Exchange, which has a courtyard filled with bookshops and antique dealers. Even if you don't want to buy anything, it is very nice and peaceful to just take a stroll through the courtyard and look at the old buildings. When walking through Old Lille you will notice most or all of the streets are cobblestone. If you look closely you will be able to see ruts where the wheels of horse-drawn carriages used to roll by. The Museum of the Hospice Comtesse is a nice place to check out as well. This was founded in 1237 by the Countess of Flanders. Inside are many masterpieces of Flemish an Dutch influence. There aren't just paintings though. There are also antiques and appliances from centuries ago. The Musee des Beaux Arts, or Museum of Fine Arts, has some great works of art. In terms of art museums in France, it is only surpassed by the Louvre in Paris. The Museum of Fine Arts also has beautiful grounds that you can walk through. This is a great way to spend an afternoon.
