The Reformed Chucrh in Slochteren - located on a raised cemetery - exists of remnants of a13th century Romanesque-Gothic cross-naved church; the transept of the original church has been preserved. This part of that building has been considerably rebuilt in the 18th and 19th century; especially after a fire in 1880, where only the outside walls were spared. Only a rather small hall church remained.

The impressive - nowadays free standing - tower (PiP) is the only part that has been preserved from the original 13th century church. It has a gable roof and has a church bell from 1373, which was made for a monastery. The church bell was bought in 1829.
