Vale Royal was, from 1974 to 2009, a local government district with borough status in Cheshire, England. It contained the towns of Northwich, Winsford and Frodsham.

Castle Park House is a former country house surrounded by extensive grounds in the market town of Frodsham in Cheshire, England. It is reputedly built on the site of Frodsham Castle, and originates from the late 18th century. It was extended in the 1850s, and its gardens were laid out by Edward Kemp. The house and most of the associated park land is held subject to the terms of a charitable trust - the Castle Park Trust. Cheshire West and Chester Council is the sole trustee of this trust. That council owns the 'top field' outright. The house and park land are used for a variety of functions. The house and park land are 'listed' in other words given special protection in planning law.
