Notre Dame du Sablon, also known as the Church of Our Lady of the Sablon, is a Gothic-style church located in the Sablon neighborhood of Brussels, Belgium. It was built in the 15th century and is renowned for its intricate architecture and decorative details.

The church was constructed between 1434 and 1450 and was designed by architect Jean van Ruysbroeck. The exterior is characterized by a striking façade with ornate stone carvings, elaborate spires, and intricate tracery work. The interior features a nave and two side aisles, with a vaulted ceiling and towering stained glass windows that flood the space with light.

One of the most notable features of the church is its collection of art and artifacts, including sculptures, paintings, and tapestries. The altarpiece, created by Jacques de Lalaing and his son, is considered a masterpiece of Flemish art. Other notable pieces include a statue of the Virgin Mary and Child by Jean Del Cour, a pulpit carved by Hendrik Frans Verbruggen, and a series of tapestries depicting scenes from the life of Christ.

The church has undergone numerous restorations over the centuries, including a major renovation in the 19th century that involved the installation of new stained glass windows and the restoration of the façade. Today, Notre Dame du Sablon remains a popular destination for visitors to Brussels, as well as a significant place of worship for the city's Catholic community.
