Grote Markt, Medieval central square in Leuven, Belgium.

The Grote Markt is the main square of Leuven, a city in the Belgian province of Flemish Brabant, bordered on two sides by the Town Hall and St. Peter's Church. The rest of the square is lined with old guild houses, giving it an enclosed shape that opens toward the church.

The square has existed in its present form since the 14th century, when the Old University of Leuven was founded. Its buildings are mostly in Brabant Gothic style, with the Town Hall as a prime example. The Meyboom planting, a tradition going back seven centuries, recalls a folkloric feud with Brussels.

The square hosts the annual flower carpet, each year with a different theme, such as the 2007 bicentennial of the Leuven fire department. In 2005, an administrative mistake scheduled the start of the Jef Scherens cycling race on the flower carpet; mayor Louis Tobback moved the start to the edge and made cycling the carpet's theme. The Meyboom, a large birch tree, is planted yearly, a tradition going back seven centuries linked to a feud with Brussels.

The square is easy to reach on foot from most of the city center and serves as a natural starting point for exploring the old town. Arriving in the morning gives a calmer experience, while evenings bring more activity around the terraces.

The Town Hall facade is covered with statues added in the 19th century to fill niches that had been empty for centuries, replacing originals that were never made. Most visitors assume the figures are medieval, but they are far more recent than the building itself.
