Landsfort Herle was a fortification with a moat in the centre of Heerlen, Netherlands (roughly the current Pancratiusplein).

Landsfort Herle appears to be the only Kirchenburg in the Netherlands (not to be confused with Wehrkirchen or fortified churches, which are more numerous, but lack the curtain wall).

The fort had three gates and two towers; the belfry of the church and the Schelmentoren, both with 2 metre thick walls.

[2] Small rooms were built into the rafters of the church, to provide shelter for the inhabitants of Heerlen during hostilities.

Unfortunately these rooms were destroyed when a supposedly German bomb strucik the church on New Year's Eve 1944/1945.
