VOC captain and governor Adriaen Maertensz Block lived there in his retirement years in the 17th century in the country house which he had let built in 1641.In the 19th century, the Baron and Baroness Van Pallandt assigned the landscape architect Jan David Zocher and his son Louis Paul Zocher, who had also worked on the Vondelpark, to design the grounds around the castle.The garden was established in 1949 by the then-mayor of Lisse. The idea was to present a flower exhibit where growers from all over the Netherlands and Europe could show off their hybrids – and help the Dutch export industry.Different gardens and garden styles go hand in hand at the Keukenhof. For example, the English landscape garden with winding paths and unexpected see-through points. There is a Historical Garden, an enclosed garden where you can see many old types of bulbs.
