Tenbosch Park, Public park in Ixelles, Belgium.

Tenbosch Park is a two-hectare green space in Brussels's Ixelles district with over one hundred notable trees. Winding pathways connect the landscape and lead past multiple water features distributed throughout the grounds.

The Semet-Solvay family bought the estate in 1885 and built a château there. From the early 1950s the dendrologist Jean-Louis Semet enlarged the garden plot by plot, demolished the château and replaced it with what is now the Indian embassy at Chaussée de Vleurgat 217. With his gardener Hector Noyer he turned the grounds into a private arboretum between 1953 and 1980. After thirty years of failed development schemes, the Comité de quartier Tenbosch, founded in 1972, helped save the land; the Brussels Region bought it and the park opened to the public in June 1985.

The park began as the private arboretum of dendrologist Jean-Louis Semet, who from 1953 to 1980 enlarged the garden with his gardener Hector Noyer, planting species from British and American nurseries. The Tenbosch neighbourhood committee, founded in 1972, campaigned against the building projects and secured the site as a public park.

The park lies between Chaussée de Vleurgat and the Rue Hector-Denis and Rue des Mélèzes, in the former Semet-Solvay estate grounds. It opened to the public in June 1985, after the Brussels Region bought the land in 1981 on the initiative of the Tenbosch neighbourhood committee. The layout was drawn by painter and architect Konstantin Stefanovitch and the works carried out by René Pechère.
