Tarleton is a village and civil parish situated in the Lancashire mosslands north east of Southport, and to the south west of Preston, in North West England. The village is known for farming due to its rich soil quality. The River Douglas runs northwards to the east of the village, which is locally thought to be where the Vikings camped on the river banks of what is now Tarleton. The parish also includes the village of Mere Brow and the hamlets of Sollom and Holmes.
