ATH or AATH, ancient town, province of Hainaut, Belgium, on the left bank of the Dender. Pop. (193o) io,6o6. The fort ress was dismantled after 1858 and its ramparts superseded by boulevards. The fine church of St. Julien ( 14th century) was destroyed by fire in 1817 (since rebuilt). A tower (Tour Bur bant) farming part of the donjon of the fortress erected by Baldwin IV., count of Hainaut, about I15o, is thus the sole medi aeval relic. Ath is famous for its gild of archers ; and the town militia has the privilege of being armed with bows and crossbows. Ath is also well known for its annual fête called le four de du casse—ducasse being the Walloon word for kermesse (fete)— held on the fourth Sunday in August. A procession escorting fig ures of two giants—Goliath, called locally Goyasse, and Samson, forms the chief feature of the celebration.
