In time, they grew intae fower veelages, Vágur, Myrkjanoyri, Gerðar an Uppsalar, that feenally merged tae form the toun of Klaksvík in 1938. Wha triggered the development o the toun wis the establishment o a centralized store for aw the northren islands on the location.

Christianskirkjan built 1963, is the first ane in Scandinavie tae be built in Auld Norse style. The roof construction is the same as the ane you wad fynd in the Viking haws, an the same which haes survived in the Faroese smoke rooms (kitchens) an in the Faroese veelage kirks. This open roof construction haes pruivit tae be especially suitable for kirk biggins, as the acoustics in this kirk is better than in ony ither o a similar size. The kirk is dedicatit tae the memory o the sailors who lost their life durin Seicont Warld War.
