One of the original heritage buildings at Tour & Taxis designed by Ernest van Humbeek in 1903, the Royal Depot (Entrepôt Royal) was originally intended for storing goods under the supervision of municipal authorities. The advent of rapid transit made this function obsolete by 1987, when the depot was decommissioned.
The Royal Depot was the first building brought back to life by Extensa in its ongoing redevelopment of the Tour & Taxis site, and renovations were completed in 2005. In the time since, the building has contributed greatly to the regeneration of Tour & Taxis, and is now home to over 40 companies with roughly 4.000 employees among them, along with bars, restaurants, cafés and retailers.
