Saint John the Baptist Church, Gothic church in the Great Beguinage of Leuven, Belgium.

Sint Jan de Doper is an early Gothic basilica with Romanesque elements, built of pale stone with bands of darker brown sandstone near the base. Its western facade is divided into three parts, with a pointed portal below a tall pointed window of five lancets, and an octagonal stair turret with arrow slits and a stone spire at one corner. The church has no tower; a slender octagonal roof turret with a slate-covered spire rises above the flat eastern chevet.

Construction of Saint John the Baptist Church began in 1305 and spanned over a century, with the eastern sections built in the 14th century and western parts completed between 1421 and 1444.

The church served the beguine community of the Great Beguinage, lay religious women who lived evangelical lives without traditional monastic vows, representing a unique form of medieval female spirituality.

The church is open to visitors from April 1st to September 30th, Tuesday to Friday from 1:30 PM to 4:30 PM, offering free entrance and a 360-degree virtual tour experience.

The church has no tower, as was customary for mendicant and beguine foundations. Instead a slender octagonal roof turret carries a carillon installed in 1998, with 16 bronze bells that ring well-known folk melodies at fixed intervals through the day.
