Sankt Laurentii is one of the best-preserved medieval stone churches on Sweden's west coast — a low whitewashed building dating from the 14th century, set in a graveyard down on the old wooden-town side of the Ätran. The interior is unusually rich for its size: a Renaissance pulpit, a 17th-century altarpiece, and frescoes from several centuries layered on the walls and vaults.
What makes the church worth seeing is the survival itself. Falkenberg's old centre was mostly timber and burnt repeatedly over the centuries; this one stone building from the 1300s has somehow outlasted every fire. The church is usually open in summer and worth ten quiet minutes.
