In the heart of Ath, Belgium, the majestic processional giants—Goliath, Tambour and Titan—have paraded through the streets for centuries during the UNESCO-listed Ducasse
Ath — Giants' Hidden Charter
You are a royal historiographer, secretly dispatched by Empress Maria Theresa to Ath in 1767 Hainaut.
Your mission: uncover the true origins of the three giants Goliath, Bayard, and
Uncover the secrets of Ath's Giants Ducasse, a UNESCO procession since 2005 where Goliath, Bayard and the Drum reveal their mysteries since 1767.
The story that haunts this land
Facing Ath's Town Hall, built between 1745 and 1756 in neoclassical style, you discover the first traces of your investigation. This monumental facade adorned with Ionic columns, listed as a historic monument in 1953, houses in its tower an 18th-century clock that witnessed the era when the giants were created. The municipal archives preserved here reveal the official commissions of 1767 for Goliath and the Drum, but strangely, no trace of who was the true commissioner.
Saint-Julien collegiate church, 14th-century Gothic with its 72-meter bell tower completed in 1784, becomes your second clue. Its historic 1776 organs, restored in 2001, still resonate with masses celebrated before ducasse processions. In parish registers, you discover that the priest of the time, Abbé Desmoulins, blessed the giants each year since the 17th century, but his notes mention a mysterious 'fourth giant' that disappeared.
The Giants House, opened in 1998 on Pintamont Street, preserves the Belgian national treasures that are Bayard the horse from 1768, Goliath from 1767 and the Drum from 1767. Curator Laurent Dubuisson leads monthly visits on the first Sunday, revealing that these giants hide period parchments within their internal structure. Your investigation reveals that a secret charter, signed by Charles de Ligne, Prince of Arenberg and Lord of Ath, could explain their mysterious creation.
The Burbant Tower, remnant of medieval fortifications from 1380 standing 30 meters high, leads you toward the truth. Built under the order of the Counts of Hainaut and listed in 1937, it guarded the ramparts that encircled the city until the 19th century. In its stone archives, you discover that Louis XIV, during the conquest of Hainaut in 1667, had ordered the construction of Vauban ramparts over 42 hectares, but also the preservation of certain local traditions to appease the population.
On Ath's Esplanade, landscaped in the 19th century on the former rampart glacis, facing the 2 hectares that host the Ducasse every two years, you assemble the puzzle pieces. The hidden charter reveals that the giants were created not by folklore, but as diplomatic symbols: Goliath representing French royal strength, Bayard the loyalty of the Athois, the Drum the call to unity. Your archivist mission ends with this discovery that forever transforms your vision of Ath's Giants Ducasse, a UNESCO procession that has perpetuated since 2005 a 250-year-old secret.
