This is the Dutch Reformed Ursus Church in Termunten, a village in the north east of the Netherlands at the Dollard Bay which is part of the Wadden Sea. The church dates back from the 13th century and was most likely dedicated to the Militairy Saint (or Warrior Saint) Ursus of Solothurn.
The Ursus church was much bigger once, until the 16th century the building was a so called cruciform church (in Dutch: 'kruiskerk'). When you look at the first photo, parts of the those walls can still be seen. In that same century the monastery next to the church was burned down and then demolished.
I'm linking to Inspired Sunday.
