gemeente (municipality), western Netherlands. It lies along the Ring Canal, which borders the reclaimed Haarlem Lake polder, drained between 1840 and 1852. Heemstede is chiefly a residential suburb for Amsterdam and Haarlem. Many dunes in the vicinity have been leveled, and the land is used for bulb cultivation. Among the town's 17th- and 18th-century country houses is the Hartecamp estate, where Carolus Linnaeus (Linnaeus, Carolus), the Swedish botanist, worked in 1736–38. The Cruquius Polder Museum was a pumping station for Haarlem Lake from 1849 to 1933. Pop. (2007 est.) 25,575.
