Before Älmhult had its own church, residents worshipped at Stenbrohults kyrka some distance away. As the settlement grew around the turn of the twentieth century, the idea of building a dedicated church took hold. The foundation stone was laid in April 1929 by Bishop Edgar Reuterskiöld, and the completed building was consecrated on the first Sunday of Advent in 1930. An interior restoration followed in 1979–1980.
The church was designed by the court architect Knut Nordenskjöld and built of brick, oriented north–south. The nave has the character of a basilica, with cross vaults over the central aisle and rounded arches in the side aisles. A triumphal arch marks the somewhat smaller chancel to the south, which is lit by stained glass windows by the artist Yngve Lundström depicting the baptism of Christ and a vision of the heavenly Jerusalem. The low tower to the north carries a substantial lantern, a smaller one above it, and a spire topped with a cross and weathercock.
Much of the church's furnishings were created by the sculptor Carl Fagerberg, giving the interior a notable stylistic unity. His altar triptych shows Christ flanked by the four evangelists, with relief scenes on the cabinet doors depicting Christ in Gethsemane and Christ carrying the cross. Fagerberg was also responsible for the font, whose lid takes the form of a carved miniature of the church's own tower, crowned with a small dove, and for the triumphal crucifix that hangs at the centre of the chancel arch, showing Christ within a halo of sun rays surrounded by symbols of the evangelists.
The pulpit is a substantial piece with a tall sounding-board crowned by a figure of the victorious Christ standing on a globe; painted panels on its sides show Martin Luther, Olaus Petri and Ansgar. It is thought likely, though not certain, that Nordenskjöld also designed the pulpit, since its detailing closely matches that of the organ cases he created for the same building.
The church has had several organs over the years, reflecting changing tastes in organ building: an instrument by Mårtenssons Orgelfabrik installed at the time of consecration in 1930, a Danish-built organ from the 1970s, a small mechanical chancel organ from the 1980s, and, since 2009, a large new gallery and chancel organ built by the Italian firm Fratelli Ruffatti, said to be linked by fibre optics so that either console can control all the pipework.
