In the belfry is the sacristy with preparatory altar and at its side a piscina, into which the wine remaining after Holy Communion is poured out to trickle down into the consecrated earth of the church. On the altar is an ivory crucifix, made by the sculptor Christian Berg. On the opposite wall of the sacristy hangs a painting of Petrus, a work of the artist Erik Olsson, a member of the Halmstad Group.
