As early as the 18th century, wealthy Amsterdammers would spend their summers in plush country retreats south of Plantage on a tract of drained land called Watergraafsmeer. The last survivor of the era is Frankendael, an elegant, restored Louis XIV–style mansion. The formal gardens behind the house are open to the public.
Staff hold a free open house every Sunday from noon to 5pm when you can explore the building on your own, or go on a guided tour (in Dutch; it departs at noon). Often there's an art exhibition going on to boot. The Merkelbach cafe sits in the adjoining coach house and its patio overlooks the gardens. Be sure to view the house's forecourt with its gushing fountain and statues of Bacchus and Ceres.
