[2] The monument, which is clad in Portland stone, was designed by Capability Brown and built by Philip Pear,[3] at a cost of £2,000,[4] for William Pitt as a monument to Sir William Pynsent,[5] of the Pynsent Baronets.

There is a legend that Pynsent was grateful to Pitt for opposing a ten shilling tax on a hogshead of cider (1763 Cider Bill), which would have affected his business, so on his death he left his entire estate to Pitt.

Pitt certainly opposed the tax, but that was because the legislation would have allowed the Revenue men to enter people's homes to check whether cider was being made, and he believed that an Englishman's home is his castle and no-one should enter uninvited.

In June 1948 it was reported that a heifer climbed the 172 steps to the top of the monument, but was later returned safely to her hillside pasture.

[8] The tower was restored in the 1990s by the John Paul Getty Trust and English Heritage.
