After he became a widower, Huygens bought land on the Vliet in Voorburg with plans to build a summer home. At the time it was quite fashionable to have a summer home on a river or canal, and old maps of Voorburg show Hofwijck as one of many. The building itself and the gardens were designed by Huygens himself in cooperation with the architect Jacob van Campen. The estate was to be "a harmonious piece of paradise on earth, with a garden in God’s image and likeness." Huygens was very much inspired by the works of classical Roman architect Vitruvius. Pieter Post was in charge of the actual building activities. The building was erected in unplastered brick and is in the Classicist style. It stands in the centre of a square swan pond. Hofwijck was inaugurated in 1642 in the company of friends and relatives.
In the collection on display are various items from the Dutch Royal family that have to do with the work of either Constantijn or his son Christiaan. In the display room for Christiaan, various types of clockworks are shown, as well as some original clocks. Family paintings and furniture are on display throughout the building, and the library of Huygens contains many of his books, and offers the same strategic view out of the window at any boat that may appear.
After Constantijn's death
When Constantijn died, his son, the scientist Christiaan Huygens, came to live there. In 1750 the last Huygens to live there sold it. Grossly neglected in later years, it was auctioned for demolition in 1849, which was avoided when it was acquired by politician Guillaume Groen van Prinsterer. The "Hofwijck Association" acquired it circa 1913, when demolition loomed again. It is now a museum, which opened its door for the first time on June 12, 1928. It closed its doors in 1995 for restoration of the gardens and building and reopened since May 31, 2005 in presence of Beatrix of the Netherlands. On November 4, 2002 Hofwijck became a registered Monument as number 508184.
Trivia
Huygens had Hofwijck built so he would have a place to escape the tensions that life as a politician brought with it, and its name reflects this: "hof" means " court" and "wijck" means "escape". However, it has more than one meaning, because "hof" can also mean "garden" and "wijck" can also mean "place". The Latin name has a double meaning too: Vitaulium means "garden of life" as well as "garden of Vitruvius".
From 1950 to 1970 this house was on the Dutch 25 guilder note.
Until 2006, the Dutch intercity trains stopped in Voorburg. This was the condition requested of the Dutch railway board by the city of Voorburg, when they gave a large piece of the garden to the building of the rails in the 19th century.
