Tower Hill is a hamlet that lies one mile south from Horsham on a ridge of land containing a sandstone known as Horsham Stone rising above the town. Tower Hill consists of housing dating from medieval to late 20th century.
It has a public house called the Boar's Head, formerly the Fox and Hounds.
It was once part of the county of Surrey in 1758 until a change in boundaries through the parliament act in 1867. The town is the centre of the parliamentary constituency of Horsham, recreated in 1983.
Jeremy Quin has served as Member of Parliament for Horsham since 2015, succeeding Francis Maude, who held the seat since 1997 but retired at the 2015 general election.
Horsham holds the UK record for the heaviest hailstone ever to fall.
