Sankt Mortens Kirke (St Martin's Church) stands at the heart of Randers' old town, a substantial red-brick Gothic structure whose interior rewards a visit. The church has been in continuous use since the medieval period and retains original carved altarpieces, tombstones, and memorial plaques that read as a record of the town's history.
The building's exterior is characteristic of the Jutland Gothic brick tradition — no stone was available locally, so the builders worked in brick with a precision and decorative ambition that makes these churches architecturally distinctive. Inside, the scale is impressive and the light good. The church is open to visitors during the day; services are still held regularly.
