Read this: A large indoor shopping centre Hoog Catharijne (nl) is located between Utrecht Centraal railway station and the city centre. The corridors are treated as public places like streets, and the route between the station and the city centre is open all night. In 20 years from 2004, parts of Hoog Catharijne will be redeveloped as part of the renovation of the larger station area. Parts of the city's network of canals, which were filled to create the shopping center and central station area, will be recreated. The Jaarbeurs, one of the largest convention centres in the Netherlands, is located at the west side of the central railway station.
