The first place of worship in De Haan Center was the Willibrordus Chapel of 1897, located between Dantelaan and Montaignelaan. Due to the increase in both population and tourism, this chapel soon became too small. Pierre Borre, a lawyer in Brussels and a landowner in De Haan, took the initiative to build a church in 1899. The Augustinian Fathers from Ghent provided the services and built a monastery along Grotestraat (number 10). In 1934, a new transept and choir were added, giving the church the shape of a Lorraine cross in honor of Saint Monica. You can see the patron saint depicted in the frontal above the main entrance, with the inscription "SANCTA MONICA ORA PRO NOBIS" and "ORD. S. AUGUSTINI HAAN AAN ZEE."
The three-aisled church with a modest octagonal tower is designed in the neo-Gothic style with some characteristic accents from Byzantine art. The furniture is simple, including confessionals, collection boxes, a communion rail, and a Stations of the Cross. In the choir, you can find stained glass windows depicting saints. Noteworthy is the bas-relief Stations of the Cross. The organ (1968) was created by Jos Loncke and sons.
