Although this church, as @JP writes, originally dates back to the 16th century, there was already a church dedicated to Saint Dionysius in Geluwe before that time; first mentioned in the 12th century. In 1148, Bishop Anselm of Tournai donated the altar of Geluwe to the chapter of Saint Peter's in Lille.
Over the centuries, the church of Geluwe changed deanery and diocese several times: from the diocese of Tournai, to that of Ypres, then Ghent, and finally Bruges.
The church's rich collection includes several 18th-century paintings, such as the Descent from the Cross (c. 1705), the Adoration of the Shepherds, the Martyrdom of Saint Sebastian, and Jesus with the Supper at Emmaus. There are also two 18th-century statues: Saint Roch and Saint Dionysius. The church also has a collection of religious textiles, including a number of (almost) complete vestments that are well-preserved. A vestment is a collection of liturgical vestments made from the same fabric or print. Such a vestment consists of, for example, a cope, a chasuble, (often two) dalmatics, accompanying stoles and maniples, a bursa, a chalice veil, and so on.
