Walton Hall was a 17th-century historic country house, set in a 300-acre (1.2 km2) estate, which was demolished in the early 20th century. Sometimes referred to as Walton Old Hall, it was situated at the centre of the Walton Hall Park in Walton (formerly Walton-on-the-Hill), Liverpool. Its former residents were Liverpool merchants and the last two families to reside at Walton Hall profited from the Atlantic slave trade. In the 19th century it was the home of Thomas Leyland during his second and third term as Lord Mayor of Liverpool.
