Lieven de Key (1560 – 17 July 1627) was a Dutch renaissance architect in the Netherlands, mostly known today for his works in Haarlem. His style is described by Simon Schama as Mannerist.^[1]

Biography

De Key was born in Ghent, and was already a well-known architect when the Haarlem council invited him to become city architect in 1592 to succeed Wouter den Abt. He brought to Haarlem the same Dutch renaissance style that Hendrick de Keyser brought to Amsterdam. Everything attributed to him or his followers, whether a building, a doorway, or merely a gable stone, is considered a rijksmonument today.

The reason so many buildings in Haarlem can be attributed to him is because Haarlem had suffered a severe fire in 1576 that destroyed a third of the city, and plans were underway for large city projects when he was appointed city architect. Before working in Haarlem and Leiden, De Key had worked in London from 1580–1591.^[2] He died in Haarlem, aged about 77.

In more recent times, many street names, buildings and e.g. one of the largest housing companies in Amsterdam,^[3] have been named after him.
