Grand'Place Samer

Highlight • Other

This market town is famous for its strawberries, which have been cultivated for over a century. There is also an annual Strawberry Festival celebrated throughout the region. The Grand'Place, the rectangular village square, is lined with old houses, mainly from the 18th century. Samer owes its name to H. Wulmaars, a monk who founded a Benedictine abbey here in the 7th century.

Samer and the Saint-Martin Church

Highlight • Religious Site

The 15th century church, a remnant of the abbey, has an octagonal bell tower and an 11th century Romanesque baptismal font. The structure is remarkable for the buildings that are built against the church, not unusual in the Middle Ages.
