Bastogne: This town near the Luxembourg border was the site of a huge battle during the Battle of the Bulge in World War II. Now there are several museums dealing with the war. The central square is "McAuliffe Square", named after the American general who answered the Nazi order to surrender with the single word – "Nuts".
Bruges: Bruges was the center of textile weaving in medieval times, and a great seaport trading center in the 15th century, but its sea lanes silted up. Much of what was built in the town when it was prosperous still remains. This was 15th century artist Hans Memling's home town. One museum in a medieval hospital, Saint John's, is named after him and contains several of his works.
Ghent: This large city has an "antique" core with a number of beautiful churches. Its most precious possession is the Jan van Eyck altar tryptique called "The Adoration of the Lamb". Other sites focusing on history are the Gravenstein Castle and a 13th century children’s hospital that is now a folk museum.
Liege: This is a commercial city with several streets dating from the medieval period and beautiful private buildings, some as old as the Renaissance (14th century). It has several museums including one devoted to folk art and one to the archeology of the area.
