The Royal Greenhouses of Laeken are a vast complex of monumental heated greenhouses in the park of the Royal Palace of Laeken. The historic complex contains tropical, subtropical and cold greenhouses.

Each year, in the spring, the Greenhouses of Laeken are opened to the public, during almost three weeks. This tradition has been carried on for a century. It is an excellent opportunity to see the wonderful architecture of Alphonse Balat, the mentor of Victor Horta, and the many plants in the greenhouses. You must book your visit to the Royal Greenhouses in advance.
