The idea of building a church at Viker was first raised in 1807, though nothing came of it at the time. The proposal resurfaced in 1857, and in 1864 a chapel congregation (kapellag) was formed. The church, named after the nearby lake Vikern, was completed in 1871 and consecrated on 6 September that year by the provost Oskar Bohm of Nora.
The building is constructed in a neo-Gothic style using slag stone, rendered white. It comprises a nave with a three-sided chancel to the east, transepts to the north and south, and a tower at the western end. In 1932 the sacristy was moved from its original position behind the altar to the north transept. The chancel window, added in 1935, depicts three biblical scenes and was created by Margit Hagenfeldt-Engdahl.
Inside, two paintings by Endel Köks from 1959 hang on the west wall. The pulpit, altar, altar rail, hymn-number boards, gallery and organ façade all date from the church's construction in 1871, giving the interior a consistent character from that period. Two bells in the tower were also cast in 1871, by the Bergholtz bell foundry.
The original organ was built in 1871 by E. A. Setterquist & Son of Örebro, inspected shortly before the church's consecration, with additional stops planned soon afterwards. A new organ was installed in 1960 by the successor firm E. A. Setterquist & Son Eftr., retaining the 1871 façade and providing 16 stops across two manuals and pedal.
