An exhibition on the old Hortus Botanicus will open Tuesday afternoon in the courtyard of the Faculty of Behavioural and Social Sciences (BSS). Nowadays, the Hortus garden can be found in Haren, but until 1966, it was located behind the Heymans and Bouman buildings between the Grote Rozenstraat and Grote Kruisstraat. The opening takes place between 4:30 and 5:30 pm.
