The first settlement at Klaksvík dates back tae Viking times, but it wis no afore the 20t century that the destrict merged tae form a lairge, modren Faroese toun that became the cultural an commercial centre for the Northren Isles an the Faroe Islands as a whole.
Klaksvik is locatit atween twa inlets lyin back tae back. It haes an important harbour wi fishin industry an a modren fishin fleet. Oreeginally, fower ferms wur locatit whaur Klaksvik is nou. 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.
The brewery Föroya Bjór in Klaksvík is a Faroese family brewery, foondit in 1888. The ram haes been the seembol o the brewery syne the early beginnin. Syne August 2007, when Restorffs Bryggjarí went oot o business, Föroya Bjór haes been the anerlie producer o beer an soft drinks in the Faroe Islands.
Wi the openin o the Leirvík sub sea tunnel, the Norðoyatunnilin in April 2006, Klaksvík is pheesically linked wi the mainland o the Faroe Islands an can nou be considered ane o its key ports. Several developments are unner wey tae exploit this seembiosis, includin a new industrial pairk locatit bi the tunnel entrance. Klaksvík is hame tae Summarfestivalurin, the lairgest muisic festival in the Faroe Islands.
The Christianskirk 
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.
