Before a permanent church existed, Kockums Jernverk lent its old exhibition pavilion from the 1896 Malmö industrial fair to serve as a works chapel. That building survives, somewhat altered, northwest of the present church, later repurposed as a youth centre.
Designed by architect Herbert Kockum and built 1937–1939, the church was consecrated in 1939. Unusually, it is oriented towards the west rather than the customary east–west axis, and its tower stands not at one end but in the middle of the north side of the nave. Inside, the three-aisled space has a brick-vaulted ceiling, with a star vault over the chancel and cross vaults elsewhere.
The altarpiece, painted in 1939 by Olle Hjortzberg, depicts the Transfiguration of Christ. The crucifix on the altar was bought in Oberammergau, in southern Germany, in the 1930s, according to the parish account, though Wikipedia dates the purchase to before 1935. A plaster figure in a chancel niche represents Bishop Egino of Dalby, a missionary said to have introduced Christianity to Blekinge before his death in 1072; it was made by Stockholm sculptor Artur Johansson, who also created the Madonna and Child on the chancel's other side.
The pulpit carries reliefs by sculptor Axel Wallenberg showing scenes from the Passion, including the Last Supper and the Crucifixion. The granite font was designed by Kockum, with a bronze figure of John the Baptist on its lid by sculptor Wilhelm Gieseke, who also made two terracotta reliefs by the east door depicting Archbishop Haquin Spegel, once appointed to Ronneby, and Ansgar, missionary to the Norse and Swedes in the ninth century.
The organ, built in 1939 by A. Mårtenssons Orgelfabrik of Lund, is variously described as having 20 or 21 stops depending on the source.
