In 1347, the first mention of a 'Gasthuys' is made in Haarlem archives. After the leper colony was founded (in the name of Saint Lazarus), a new gasthuys, in the name of Saint Elisabeth, was built on the Verwulft where the sick were treated that did not need quarantine outside the city walls. This hospital grew until the fire that burned it down. Hofje van Loo was an add-on that survived. The Elisabeth Gasthuys (later called EG) was rebuilt on the location of a former monastery (cellenbroers or minnebroers) in the Groot Heiligland (across the street from the Frans Hals Museum today) where it operated from 1581 to 1971. Originally a church institution, it was now run by Haarlem council members, due to the Protestant Reformation. Since the German occupation of World War II, this hospital is no longer run by the Haarlem council, but still exists and is called the Kennemer Gasthuis today. The former buildings in the Groot Heiligland house a community center and have been converted to homes.
