The opening period for 2026 has now ended. This period traditionally takes place in spring and lasts around three weeks. The exact dates for 2027 will be announced in early 2027.

According to annual traditions, the Royal Greenhouses in Laeken will be open to visitors in spring. Beginning in 1873, Alphonse Balat, an architect and tutor to Victor Horta, designed a greenhouse complex to complement the Palace of Laeken's classical style. The greenhouses were designed to offer the silhouette of a glass city, nestled into the undulating park landscape.

Indoor and outdoor experience

Visits to the greenhouses are both an indoor and outdoor experience. Once on site, you will be able to choose between a short (2 km) or long (3 km) visit. During the evening visits, it is only possible to complete the shorter of the two.

On the long route, your visit begins with a walk through the gardens of the Royal Domain. There you will first discover the wondrous architecture of the greenhouses from afar, then explore other special spots along the way, such as the temple ruins at the edge of one of the ponds or the rose arch. Once you have completed the outdoor leg of your visit, it is time to enter the greenhouses themselves.

For the shorter visit, you will only tour around the greenhouses.

The greenhouse complex

The greenhouse complex comprises the following areas:

• The Palm Plateau with the Debarcadère, the Palm Greenhouse, the Azalea Greenhouse, the Geranium Gallery, the Diana Greenhouse and the Mirror Greenhouse.
• The Embarcadère, formerly used as a guest reception area.
• The square Congo Greenhouse with its subtropical plants.
• The Orangery, where the camellias, and orange and laurel trees are kept over the winter months, and which are currently displayed on the esplanade in front of the Orangery.

The largest greenhouse, the Winter Garden, is currently undergoing renovation and is not accessible. However, for the first time this year, you will have the opportunity to explore the Grand Gallery of Honour at Laeken Castle at the start of your tour.
