S. Clemens Church

A chapel dedicated to Willibrord was founded in 1897, but it became too small for the growing amount of churchgoers when De Haan developed into an important seaside resort. The construction of a new, fully-fledged church was completed in 1902. This church soon became too small as well. Therefore, a new transept and choir were built in 1934.

A chapel in Wenduine was first mentioned in 1135. This became the parish church around 1185. Originals parts of the old church can still be found in the south choir and the substructure of the tower. The church underwent its first renovation in the first half of the 13th century. The building was expanded with side aisles and side choirs around 1290. The tower, which also served as a beacon for shipping, was raised between 1546 and 1547. The church was destroyed by the Iconoclasm in 1566. The church was used by the army as a horse shed from 1607. The restorations of the church took place two years later. The church was reduced in size because the number of parishioners had greatly decreased. After Wenduine had developed into a seaside resort, around 1900, the number of churchgoers increased again. A new western part of the church was built in 1906.

The Synagogue in Ostend is an Ashkenazi synagogue built in 1910-11 by architect Joseph De Lange. This stone building still serves as a synagogue.
