Hallgrímskirkja

Hallgrímskirkja is a Lutheran parish church in the heart of Reykjavík and the largest church in Iceland. Visit Reykjavík describes it as the city's most recognisable building, inspired by basalt columns and lava flows, and as a compass point for finding your way around downtown.

It is still a working church rather than just a viewing platform. The tower gives sweeping views over the rooftops towards the harbour and bay. Rainbow Street leads down from the church to Laugavegur, the main shopping street. Opening hours and tower access change with services and events, so check the church's own website on the day.
