Irenekerk
Now a church building of the Protestant Community of Bierum, Holwierde and Krewerd. A straight-closed hall church with round-arched windows and a roof turret, divided by lesenes, built in 1890 by contractor Scheltens. The partly open roof turret was renovated in 1971. The interior was radically changed in 1987 to a design by architect JA Jongman.
