The original village (inhabited since Saxon times) is clustered around St. Mary's church, whose churchyard contains an ancient yew. Much of the surrounding land was once owned by the powerful Stanley family. In the Victorian era a ferry brought visitors from Liverpool to the pleasure gardens, remnants of which can be seen in Eastham Country Park. Eastham Lock forms the western end of the Manchester Ship Canal. In the 1930s, significant housing development joined Eastham to neighbouring Bromborough leaving the Mersey side of Wirral continuously built up to New Brighton.
Eastham is considered the "Gateway to the National Seashore" with the Salt Pond Visitors Center, the Nauset Marsh hiking Trails and two beaches, Coast Guard and Nauset Light.
