According to an early manuscript of the Västgöta law, the church site at Friggeråker was designated by the missionary Saint Sigfrid in the early 1000s. Local tradition suggests several churches have occupied the spot since then, though such early accounts should be treated as tradition rather than confirmed fact. The first building was probably a timber stave church, followed by a stone church constructed during the 1100s or early 1200s. That medieval church burned down in 1566, was rebuilt, and was eventually demolished in 1871. Its ruins remain beside the present building, offering visitors a tangible link to the site's long history.
The current church was designed by architect Rolf Bergh and completed in 1955. It is built of grey limestone with a roof of black slate, giving it a restrained, modern Nordic character quite different from its medieval predecessor. Inside, the walls are whitewashed, while the altar wall and the single vault spanning the whole nave are constructed in yellow-red facing brick, creating a warm contrast within the otherwise plain interior.
Among the church's furnishings is an altar cabinet dating from the 1700s, brought over from the earlier church that stood on the site. The limestone font, carved by the so-called Ottravad Master, takes the form of a seven-petalled flower and holds a silver bowl depicting the seven rivers of paradise. Above it hangs a silver crown symbolising the Trinity, suspended as if from a heavenly ladder.
The wrought ironwork on the church doors is particularly distinctive, depicting a sequence of scenes: a pagan temple in flames, Saint Sigfrid's mission, the old medieval church, and the surrounding countryside together with the new church—a visual summary of the site's own history worked into the entrance itself.
