St Ansgar's Chapel is entered beneath the two towers, on the gable end of Högalidskyrkan as you come up Högalids kyrkväg. The church's main entrance is on the other side of the church.
The chapel, which seats around 50 people, is well suited for baptisms, funerals and weddings. Mass is celebrated here on Wednesdays at 12.00.
Behind the altar is the artist Einar Forseth's mosaic "Pieta". Candlelight highlights the mosaic and creates a warm atmosphere in the chapel. The chapel is bright, with dark wooden features.
