Dutch cities that flourished during the Middle Ages all have hofjes, best translated as courtyards. Although many have disappeared over the course of the centuries, the city of Groningen still boasts nearly three dozen hofjes. These groups of houses surrounding an inner courtyard or square are not only wonderful to explore, but also of historic significance. Many of these institutions were created to care for the sick and elderly or to accommodate pilgrims. The oldest of these dates back to 1267, while the most recent addition was built in 1939. You can get a map of the the most scenic ones at the tourist information centre.
