You really must visit the famous cathedral.
Strasbourg's Gothic cathedral is regarded as one of the most important works of Occidental architecture. The sculptures on the west façade are particularly impressive. The awe-inspiring interior is illuminated by the coloured light of the superb windows, made of 50,000 individual pieces of glass. The sunlight entering from a very particular spot forms a green ray indicating the precise moment of the day and night equivalence on 20 March.
