Leasowe Castle may have been built for Ferdinando Stanley, 5th Earl of Derby[6] – a patron of Shakespeare – in 1593, possibly (though this is disputed) as an observation platform for the Wallasey races which took place on the sands in the 16th and 17th centuries, and which are regarded as a forerunner of the Derby races. Ferdinando's brother William, the 6th Earl, was described as a noted sportsman and is remembered as a keen supporter of the Wallasey races.
