Leason farm is situated on the northern coast of the Gower Peninsula, about five miles south of Llanelli. On the current edition of the OS map the farm is divided into two Leason Farms, a Middle Leason and a Lower Leason. On the first editions of the 25inch and 6inch OS maps (published in 1879 and 1883-1884 respectively) Leason is spelled 'Leaston.'
