Prinsenhoftuin. Groningen, the Netherlands.

"During the Middle Ages, Prinsenhof was the property of the Brethren of Communal Life, a religious faction... By the end of the 16th century Prinsenhof became the official residence of the Nassau viceroys, giving the building its current name...  In this period the Prinsentuin Gardens were created. The letters W and A, cut from taxus hedges, refer to viceroy Willem Frederik and his spouse Albertine Agnes." Source: Prinsenhoftuin Hotel Site.
