Escape Room Groenlo

The Siege of Groenlo (also known as the Siege of Grol) in 1627 was a siege set up by Prince Frederik Hendrik of Orange of the fortress occupied by the Spaniards during the Eighty Years' War. The siege lasted from July 20 to August 19. Part of the siege was the construction of a circumvallation line around the city, to prevent Grol from receiving reinforcements, to store supplies and ammunition and to prevent a dismay. Hendrik van den Bergh, a Dutch nobleman in Spanish military service and a full cousin of Frederik Hendrik, tried to relieve Grol with a large army, but came too late. Grol would remain state until the end of the war.
