The granite walls of Trönö Gamla Kyrka, about 15km northwest of town on Rd 50, have been left virtually untouched over the years – it’s just been added onto, so the oldest part of the church, dating from the 13th century, is still intact. There’s a free-standing wooden bell tower and a well-preserved wooden roofed wall surrounding the church. Take bus 67 (Skr35, several daily).
