It is worth exploring the Guillemins district after visiting the station itself (see the description of visit no. 23). The area owes its name to the Hermits of Saint William, a monastic order which was present in the neighborhood from the 13th century to the 16th century. The latter half of the 19th century saw the district grow around the station, built in 1842 on the railway line from Liège to Brussels. At the time of the Belle Époque, the city was blooming in the wake of the 1905 World's Fair. Discovering the Art Nouveau facades and the urbanology of the neighborhood will give you a taste of this period.
