The foundation was established in 1949 with the aim of building student accommodation and a church in Uppsala. Funds were raised over the following decade, and the foundation stone was laid in 1959 by Archbishop Gunnar Hultgren. The church itself was consecrated on Lady Day 1961 by Bishop Johannes Sandegren, acting on the archbishop's behalf, and was dedicated to the missionary Ansgar. As congregation numbers grew, the building was extended in 1997 to designs by architect Gösta Wikforss, with a further alteration in 2016 adding the present sacristy.
Constructed of rendered brick with a nave and two side aisles, the church was designed by Gösta Wikforss. Its chancel faces east and the entrance west. Although originally whitish in colour, the exterior was repainted a strong orange around the year 2000. A freestanding bell tower, designed by Lars Ridderstedt, was added in 1999; its single bell is rung by hand using a rope, the church having previously had none.
Inside, the arrangement of font, crucifix and altar along the central axis reflects a via sacra idea, picturing the congregation as a pilgrim people on the move. A marble font by Erik Sand dates from 1963, and a large crucifix, some 3.5 metres high, is the work of Sven-Bertil Svensson. The altar wall bears a cross-shaped icon of Christ painted by Erland Forsberg in 1984, flanked by icons of the Virgin Mary and John the Baptist; matching icons either side were added as recently as 2025, painted by Robin Johansson. Further icons around the church depict saints including Ansgar himself and Birgitta of Sweden, and there are spaces for candle-lighting before a Marian icon and an icon referencing the Emmaus story.
The church has had a changeable relationship with its organs. An early small positive organ, bought in 1965 from a Danish workshop, was later replaced in 1993 by an instrument transferred from a now-closed chapel elsewhere in Uppsala; that organ has since moved on again, to a parish church at Rasbo. The current organ was built in 2002 by Latvian organ builder Jānis Kalniņš, funded through a bequest to the foundation.
All the church's fittings have been donated, and its work is sustained entirely through voluntary giving, reflecting the foundation's long-standing character as a body dependent on gifts rather than parish funding.
