The Renaissance City Hall, designed by Cornelius Floris and built from 1561 to 1565, is an outstanding example of the Flemish mannerism that replaced the formerly supreme Gothic style. It was burned down by the Spanish in 1576 and rebuilt as you see it now. Look for the frescoes by Leys, an important 19th-century painter; some interesting murals; and in the burgomaster's chamber, an impressive 16th-century fireplace.
