The Groot Park in Lovenjoel is private property, but accessible on the marked trails.
In 1649 the de Spoelberch family acquired the village of Lovenjoel. Their 25 ha domain stretched into the valley of the Molenbeek, where they built a castle at the ends. The large castle de Spoelberch is located in the Groot Park, west of the church. The 'little' castle, or the Felixhof, is located in the Klein Park, east of the church.
The last, the Spoelberchs, had a great interest in dendrology and planted various rare tree species. In the Groot Park and the Klein Park there are still unique trees such as swamp cypress, rare species of oak, beech, a zelkova and a magnolia grandiflora.
After the last scion died childless, the domains came into the possession of the University of Leuven in 1915, who in turn leased the domain to the Sisters of Charity of Ghent. They built an institution for mentally ill women and psychiatry students, Salve Mater, in Groot Park on the north side.
The possibilities to continue working on modern and efficient psychiatric care within this framework became less and less good. It was therefore decided to have all patients leave for other institutions or transition homes from the 1990s. The buildings came into the hands of VIRIX from 2008, who, while respecting their monumental character, are converting the historic buildings into modern lofts with limited space downstairs for services and service companies.
