History

Wiltcher's owes its name and origins to Sydney-Charles Wiltcher, the son of English immigrants, who was engaged by the owner, Baron Joseph de Crawez, to begin work on a Beaux-Arts building on Avenue Louise in the early 1900s. The architect Georges Delcoigne worked on the building in 1911–1912, according to the Brussels regional architectural heritage inventory, and the metadata of a Wikimedia Commons photograph of Avenue Louise 71 independently credits the work to architect Georges Delcoigne, anno 1911–1912. The hotel opened to travellers in 1913 and, set on the avenue, its facade was designed to project a sense of Old World dignity. In 2023 the hotel publicly marked its 110th anniversary, consistent with the 1913 opening.

Over the following century the property passed through several identities and became a landmark address on Brussels' golden-mile shopping street in Ixelles. According to the Brussels heritage inventory, the present-day Wiltcher's ensemble — a large postmodern complex combining a hotel, shops, offices, apartments and parking — was built around 1990–1993 by the Atelier d'Architecture de Genval, integrating several older facades, including the historic Beaux-Arts and Art Nouveau frontages along Avenue Louise. The hotel operated as the Conrad Brussels until 2012, after which it was taken over by the German luxury group Steigenberger, reopening under the Wiltcher's name and today branded the Steigenberger Icon Wiltcher's. The inventory classifies the resulting ensemble under the Postmodernism, Eclecticism, Beaux-Arts and Art Nouveau styles, reflecting the layering of the original early-20th-century hotel within a late-20th-century reconstruction.
