Sint-Nicolaaskerk, Gothic parish church in Sint-Niklaas, Belgium

Sint-Nicolaaskerk is a five-aisled Gothic church on the east side of the Grote Markt, with a grey stone facade, a steep central gable and a slate spire topped by a cross. Inside, clustered pillars rise to pointed ribbed vaults, and a large altarpiece with a gold-toned retable stands at the far end. The church has seven altars, a Baroque pulpit from 1706 and a 1998 organ with over 3000 pipes.

The church was established in 1217 when Bishop Gosuinus of Tournai created an independent Saint Nicholas parish, separate from Waasmunster. This founding marked the beginning of the town's religious independence.

The church is dedicated to Saint Nicholas of Myra, Saint Barbara and Saint John of Nepomuk. In the choir hang old procession banners recalling former brotherhoods, and the Baroque pulpit of 1706 is supported by a life-size wooden sculpture of Saint Nicholas.

The church stands on the east side of the Grote Markt, with the main entrance in the rebuilt west facade facing the square. The building is a protected monument, and the interior is reached through the pointed arched portal beneath the statue. Visitors should check locally before travelling, as services and events can close the church.

The adjacent Saint Nicholas Square becomes an entertainment venue during summer, with dance events on Wednesdays and concerts on Thursdays. These seasonal activities bring modern life to the historic plaza.
