By the 1960s and 1970s Upplands Väsby had grown rapidly, and the parish's older church, Hammarby kyrka, could no longer serve the expanding population. A new church closer to the centre was planned from 1970, with the foundation stone laid in autumn 1974 and the building consecrated on 7 December 1975 by Bishop Ingmar Ström.
Ahlberg drew inspiration for the design from ancient Sumerian architecture, reportedly some 5,000 years old. The result is a square building of dark reddish-brown brick with pronounced mortar joints, its roof beams left visible on the exterior and clad in copper. At the south-eastern corner stands a rectangular bell tower topped by a distinctive hexagonal copper superstructure. Inside, the church keeps a traditional east–west orientation, with the altar at the eastern end.
The interior is marked by a heavy cross-beam supporting the roof, understood to symbolise the connection between heaven and earth established through Christ's cross. Small, high-set windows and a ceiling fitted with tiny lamps evoke a starlit sky, while the floor is laid in white Italian marble. A choir room to the west can be joined to the main church space by folding walls, allowing the room to be enlarged when needed.
Among the furnishings, the free-standing altar is carved from white Italian marble in the form of a sarcophagus, raised on eight low pillars. Above it hangs a wooden Christ figure carved by Karl Göte Bejemark, completed in 1983. Nearby, the font, also of white Italian marble, bears a relief of Christ's monogram, and above it hangs a wrought-iron chandelier designed by the architect and made by smith Rune Pettersson. The 30-stop organ, built by Grönlunds Orgelbyggeri, was inaugurated in 1979, and the tower houses two bells for ringing together with a 22-bell carillon.
