For over a century, spring in Brussels has been marked by the highly anticipated three-week opening of the Royal Greenhouses of Laeken. This offers visitors a rare opportunity to explore this architectural and botanical marvel in the Belgian capital.
Designed by Alphonse Balat, mentor to Victor Horta, and commissioned by King Leopold II, the “Ideal Glass Palace” was constructed between 1874 and 1905. It forms part of the Royal Domain of Laeken, the official residence of the Belgian royal family.
A masterpiece of iron and glass designed to replicate nature, the complex resembles a glass city set within an undulating park landscape. It creates the impression of a luminous, interconnected world of domes, galleries, and arcades. Among its structures is the Débarcadère, a pier-like greenhouse built in 1886–1887 and originally designed to receive and entertain guests. It leads via a staircase to one of the most prominent spaces: the Winter Garden.
Visible from the outside, the Winter Garden will not be accessible to visitors this year, however, as it is undergoing renovation work. Built between 1874 and 1876, it was the first structure to be erected in this “city of glass”, and it houses tall palm trees, many of which date back to the time of Leopold II, beneath its 25-metre-high cupola. As compensation, this year’s visit will open with the Grand Gallery of Honour at Laeken Castle for the first time.
The wider complex comprises the Palm Plateau, the Débarcadère, the Palm Greenhouse, the Azalea Greenhouse, the Geranium Gallery, the Diana Greenhouse, the Mirror Greenhouse, the Congo Greenhouse with its subtropical plants, and the Orangery, where camellias, as well as orange and laurel trees, are kept during the winter months before being displayed on the esplanade in front of the building.
A permanent team of around fifteen to twenty gardeners is required to maintain the greenhouses and care for plants that, in some cases, have been there for over a century. The collection features some of the world’s largest and rarest ancient camellias, royal azaleas and centuries-old orange trees, whose rich fragrance fills the air. Other highlights include the impressive Victoria amazonica water lilies.
The experience is as much sensory as visual: moving between the warmth of the glasshouses, the scent of orange blossom and the filtered light through the domes makes you feel as though you are suspended between two worlds, provided you can find a spot without too many other visitors.
Practical information
The greenhouses will be open from 17 April to 10 May, with ticket sales starting on 20 March at 1 p.m. Last year, 140,000 tickets were sold within 36 hours of release, so early booking is highly recommended. Evening visits are also available from Friday to Sunday, as well as on 30 April.
5 May will be dedicated to visitors with reduced mobility.
There are two routes within the grounds: a shorter 2 km route focusing on the greenhouses and a longer 3 km route that winds through the landscaped gardens, past temple ruins by the ponds, a rose arch, and the greenhouses themselves. The longer route is unavailable in the evening. The longer route offers sweeping viewpoints over the architecture, so photographers may wish to bring a wide-angle lens.

Comfortable shoes are recommended, as the distances within the domain are considerable.
