Your investigation in Anderlecht begins at the Erasmus House, a red brick building typical of 16th-century Flemish architecture. Classified as a historic monument in 1938, this 300 m² residence was restored in 1952 to become a municipal museum. It was here that Desiderius Erasmus, the renowned humanist, spent his early years before joining the Augustinian monastery in 1475. The house's reconstructed library houses over 300 original editions of his works, a testament to this thinker's lasting influence on European culture and a major heritage site of the Brussels-Capital Region.
Continue towards the Collegiate Church of Saints Peter and Guy, a church founded in 1350 and rebuilt between 1526 and 1533 in the Brabantine Gothic style. 65 meters long with vaults 25 meters high, this collegiate church houses 16th-century stained glass windows and a reliquary shrine of Saint Guy dating from 1350. This medieval pilgrimage site was damaged by a fire in 1533, an event that marked its construction. The 72-meter bell tower, completed in 1775, still dominates the landscape of Brussels-Anderlecht, recalling the religious fervor of the era.
The path then leads you to the Beguinage of Anderlecht, a complex classified as a major heritage site of the Brussels-Capital Region in 1997. Founded in 1322 by Joanna of Constantinople, Countess of Flanders, it consists of 13 houses around a 13th-century chapel. The Beguines lived here in an autonomous community, without perpetual vows, a characteristic of the Flemish Beguinages inscribed on the UNESCO list in 1998. The Notre-Dame chapel, dedicated to the Beguine Virgins, restored in 1960, preserves 14th-century Gothic frescoes, offering a glimpse into the spiritual life and role of women in Brussels.
Your route winds through the Place de la Vaillance, the central square of Old Anderlecht, named in homage to the resistance fighters of 1940-1945. Paved since the 19th century and surrounded by 17th-18th century houses, it was a site of weekly markets from the Middle Ages and served as a parish cemetery until 1784. Nearby, the Rue du Chapitre, a medieval cobbled street mentioned as early as 1250, connects the Erasmus House to the Collegiate Church. Lined with 16th-18th century gabled houses, this street was the scene of anti-reformist riots in 1520, testifying to the tensions related to Erasmus's humanism.
Finally, the former Saint-Nicolas Hospice, founded in 1614 for the poor and pilgrims, then transformed into a local museum in 1970, concludes your exploration of Brussels-Anderlecht's heritage. 500 meters away, Astrid Park, inaugurated in 1935 in homage to Queen Astrid, offers a 4.5-hectare space with a pond and Art Deco statues. This thematic walking tour will have allowed you to discover the history of Brussels-Anderlecht, its historic monuments, and its role in the lives of figures like Erasmus. You will take with you a deep understanding of this district, a true historical circuit revealing the layers of Belgium's history.
