Your quest begins at the Beguinage of Herentals, founded in the 13th century and documented from 1267, one of Flanders' oldest. This 1998 UNESCO site, with its 89 traditional Flemish houses, was the heart of a Beguine community specializing in lace and textile work from the 15th to the 19th century. Here, amidst this medieval Beguine urbanism, the first stitches of your investigation are woven, revealing the origins of an art that brought prosperity to Herentals and the World Heritage of Flanders.
Continue your investigation at the Beguinage Church, built around 1450 in the flamboyant Flemish Gothic style. Restored in the 17th century after the Wars of Religion, it retains period Baroque furniture and carved altarpieces from the 16th-17th centuries, witnesses to Flemish religious art. The architectural details and artworks of this church, as well as the nearby Convent, a former Franciscan convent from the 16th-17th century, conceal visual clues. These spiritual edifices in the medieval city center were places of contemplation and work for the Beguines, where sacred motifs inspired their coded lace creations.
Cross the city to Sint-Waldetrudiskerk, a 15th-century Gothic edifice dominating the Grote Markt. Its 65-meter bell tower, a major urban landmark visible for about 1.5 km, guided merchants and Beguines for centuries. Dedicated to Waltrude, a 7th-century local saint and historical patroness of the region, this church houses Renaissance stained glass windows and Flemish art from the 16th-17th centuries. Every element of this Flemish historical monument could hold a key to deciphering the lace secret, connecting sacred history with textile craftsmanship.
The Grote Markt, Herentals' administrative and commercial heart since the 12th century, is your next stop. Surrounded by 16th-17th century merchant-draper houses and dominated by the Flemish Renaissance-style Town Hall (1540-1560), it was the site of a historically documented lace and textile market from the 15th to the 19th century. Clues are hidden in the architecture, guild emblems, and even the remains of the Bovenpoort, a 13th-14th century urban fortification restored in the 19th century, connecting the city center to the northern districts. Kasteel Le Paige, a 17th-century patrician residence (around 1650), owned by the high-ranking merchant Le Paige family, also attests to this textile prosperity.
Your journey finally leads you to Netepark and its Molen, a 16th-century watermill on the Nete river. This industrial infrastructure, which economically supplied lace workshops and dye houses from the 15th to the 19th century, is the culmination of your exploration. The secret of the Coded Lace, the result of centuries of craftsmanship and ingenuity, will be revealed here, by the water that nourished the city. This thematic circuit in Flanders offers an interactive visit and a deep dive into the history of Herentals, a true GPS treasure hunt through Flemish heritage.
