Tatorp Lock is an equalising/levelling lock used to balance the differences in water level between Lake Viken and the Göta Canal. The sluice gates are to this opened with a capstan. Tatorp Lock was ready for use in 1814. In the beginning, there was no bridge in Tatorp. In order to cross this part of the canal, inhabitants used a "Lina," a tiny ferry. Tatorp Bridge was not built until 1953. The bridge is from a Dutch model.
