Gann Church ruin (Swedish: Ganns Ödekyrka) is the ruin of a stone church built in the middle of the 13th century in the locality of Lärbro. The church consists of a chancel, nave and tower. The tower rests on the west wall of the nave. The tower was presumably built in the late 13th century. The church was presumably abandoned as early as in the 16th century. The chancel and arch contain mural paintings.
