A very large collection of works by René Lalique, a renowned French glassmaker and jeweller active from the 1880s until his death in 1945. The museum is adjacent to the sole production facility operated by Lalique (the company he founded), opened in 1921 and is on the site of a glass-making factory dating to the 18th century.

Vauban Dam
The Barrage Vauban is a bridge, weir and defensive work erected in the 17th century. At that time, it was known as the Great Lock (grande écluse), although it does not function as a navigation lock in the modern sense of the word. Today it serves to display sculptures and has a viewing terrace on its roof, with views of the earlier Ponts Couverts bridges and Petite France quarter.
Covered Bridges
The Ponts Couverts are three bridges dominated by four towers from the 12th and 14th centuries. The bridges got their name from their roofs, which they lost in the 18th century. The towers are the remains of the ancient ramparts.
