Church of Our Lady of Laeken

Crypt under the church, with tombs of royal family members and their spouses. Constructed under a cupola behind the choir, it is accessible with 2 staircases from the church. The monumental oak doors are engraved with mosaics of coat of arms of the 9 Belgian provinces. The central white marble tomb is occupied by the first king of Belgium, Leopold I, and his second wise Queen Louise of Orleans. The crown symbolizes the tomb of a king. Around the central tomb are the tombs of his successors and their spouses. The niches in the walls host other members of the royal family, including the regent of Belgium, Prince Charles, and other princes and princesses. The crypt was constructed as an initiative of Queen Louise because she preferred to be buried in Laken instead of in the Cathedral of St. Gudula and St. Michael closer to the city center. A contest for a design was organized and won by Joseph Poelaert (known as the architect of the monumental Palace of Justice). Construction started in 1854 and the crypt was commissioned in 1872 although the rest of the church was only finished by 1907. Because King Leopold I was not a catholic, it was decided to construct another entrance in the back wall of the crypt so that the deceased king's body didn't have to pass through the Catholic church above. The crypt is open to the public 13 days per year, and occasionally members of the royal family can be spotted in the crypt to honor the deceased with flowers. According to the legend, faint whining can be heard in the crypt, attributed to the ghost of Queen Fabiola still refusing to die.

A monument central in the Laken Park, dedicated to King Leopold I. It stands 50 m tall, symbolizing the 50 year independence of Belgium in 1880. The monument was designed by architect Louis De Curte in a neo-Gothic style, and built between 1878 and 1881. Due to delays in construction, it was not finished in time for the jubilee celebrations for 50 years independence. The monument consists of a gallery with 9 bays, one for each of the 9 former Belgian provinces, with a sculpture of King Leopold I by artist Willem Geefs in its centre. The 50 m tall structure is topped with a gilded crown. Above each of the statues representing the Belgian provinces, a lion (one of the icons of Belgium) holds an escutcheon of the corresponding province. The statues are made by various sculptors, including Thomas Vincotte, Charles Vander Stappen, Adolphe Fassin, Antoine-Joseph Van Rasbourgh, and Charles Brunin. Its isolated location has made the monument a target of vandalism, and it is now surrounded by a fence.

One of the most beautiful parks of Brussels, dating from the 19^th century as an initiative of King Leopold II. It was the kings vision to realize a large public park close to his residence in Laken. He privately purchased the land in 1876 and officially transferred ownership to the Belgian State for the construction of the park. The park was designed by German architect Edouard Keilig, who also designed the better known Ter Kameren Park. Construction took place from 1876 to 1880, in time for festivities for the 50^th anniversary of the Belgian nation. It remained a park throughout its history, with the exception of the World's Fair of 1958 when parts of it were claimed for the Fair: several pavilions were built, and the avenues traversing the park were widened. The American theater is the best known remnant of the World Fair in the park. Next to the park is the Belvedere Castle which belongs to the royal family, and is rumored to be inhabited by ghosts.

The Roal Greenhouses are a vast complex of monumental heated greenhouses in the park of the Royal Castle, containting a variety of tropical, sub tropical and temperate plants and trees. The history of the greenhouses dates back to the 18th century, when King Leopold II changed the layout of the surrounding garden and commissioned architect Alphonse Balat to design a series of greenhouses. Starting in 1874, the construction of the greenhouses took over 20 years and was finalized in 1895 with the erection of the Iron Church, a domed greenhouse which would serve as the royal chapel. The largest greenhouse, the dome-shaped Winter Garden, has a diameter of 60 m and a height of 30 m, designed in an Art Nouveau style with iron and glass as construction materials. With a floor surface of 25 000 m², the numerous greenhouses are connected with glass covered galleries and locks to retain temperature differences appropriate for the vegetation. Over 800 m³ of oil is burned each year to maintain the temperature. The botanical collection includes numerous species from Africa, although many cultivars have been lost since the death of King Leopold II. The camellias collection in particular, with over 1000 plants, is the world's oldest and largest collection in a greenhouse. The complex can only be visited by the public during a two-week period in April-May when most flowers are in full bloom, as dictated by Leopold II and followed as a tradition by all kings thereafter.

The bright red tower in oriental style stands nearly 50 m tall and hosts Japanese art from before export to the West became common. It features Imari porcelain from the 17th and 18th century, as well as 19th century lacquery, bronze vases, ivory objects and other assorted ornamental items. The exceptional blue-white vase at the entrance was donated in 1910 to the Belgian government by the Japanese emperor. The tower is the center of a replicated Japanese garden. It was known as a Tō, a Japanese pagoda, of which construction started in 1901 until its inauguration in 1905.

Monumental fountain depicting Neptune, commissioned by King Leopold II and installed in 1905 near the Royal Domain of Laken. It had been out of service since 1965, until it was restored in 2017 after 60 years of being neglected. The marble and bronze statues have been restored to their former glory. Interestingly, the fountain is an exact copy of the 400 years old Neptune fountain at the Piazza del Nettuno in Bologna, which was restored at the same time.
