Country houses

A country house, known as a buitenplaats in Dutch, is a large house or mansion, often with outbuildings, that forms a harmonious whole with a surrounding garden or park. In centuries past, this sort of house was built as a refuge from the bustling city, a place where the residents could enjoy the peace and quiet of the country. More than 600 of these country houses still exist in the Netherlands, some open to the public and others still in private hands.

Keukenhof Castle 

Keukenhof Castle is situated in the middle of an estate with a 200-hectare wood, a park, meadows and various outbuildings, such as a coach house and a playhouse. The castle was built in 1640 as the country house of Adriaen Maertenszoon Block. Over the centuries, this country house has been sold on to various, mainly Amsterdam, families, who made various renovations and extensions as required through the years. The castle’s English garden was designed by the horticultural architects Zocher, a father and son. As early as 1661 mention was made of the "Keukenhouff orchard and plantation”. The Keukenhof Flower Show, an annual event held on the northern part of the estate that attracts visitors from around the world, was first held in 1947.
