the interior is dominated by the medieval vaulting. among the furnishings, the baptismal font is the oldest, dating from the late 12th century, intricately sculpted and made of stone from the area around lake mälaren, i.e. locally. in the church there is also a carved wooden figure of a male saint, made in sweden, and an altarpiece from c. 1500 made in the atelier of jan borman in flanders. the pulpit and the pews are baroque in style.
