Sint-Salvatorkerk, Catholic church in Harelbeke, Belgium

Sint-Salvatorkerk is a church featuring classical architecture and a Romanesque-style bell tower with nine sound holes on each side. The building was structured according to classical principles and displays the craftsmanship of the 18th century.

A chapel near the count of Flanders' villa, destroyed by Norsemen in the 9th century, preceded the present church. Count Arnulf built a new church between 935 and 939 to house the relics of Saint Bertulf; it burned in 992. The fourth church was built in 1795 to plans by Laurent-Benoît Dewez, appointed in 1764, keeping the 12th-century tower and transept. The tower was dynamited on 23 May 1940 and rebuilt in 1953-54.

The church holds the Holy Thorn, a twig from Christ's crown of thorns brought from the St. Martin's Abbey in Trier by canon Pieter Willem Carpentier in the 19th century. From 1883 to 1973 a Holy Thorn procession was held each year on Ascension Day, drawing crowds to Harelbeke; it was renewed in 1958 under dean Vandeputte.

The church stands on the Gentsestraat in the centre of Harelbeke, with the memorial to soldiers of both world wars beside it. The Romanesque tower, rebuilt in 1953-54, holds a 50-bell carillon installed in 1960. The interior was fully restored in 2008-09; the crypt below is visible from above through a glass floor.

The crypt of Sint-Pieters-in-den-Crocht, the only remnant of the 10th-11th-century church, survives beneath the building and is visible from above through a glass floor panel. Excavations in 1943 and 1958 also uncovered foundations containing Roman building rubble, evidence of a destroyed Roman settlement on the site.
