The Hill Garden is a beautiful, landscaped garden, originally the private garden of the now demolished ‘Hill House’.

The house was owned by soap manufacturer William Lever - later Lord Leverhulme, who comissioned landscape artist Thomas Lawson to lay out the garden in 1905. Lever constucted a series of lawns and terraced gardens which would be out of public view, using materials from the excavation of the Hampstead northern line extension. The Pergola was constructed the fiollowing year, offering incredible views across the Heath.

The Pergola was extended several times over the years as Lord Leverhulme bought up surrounding properties, in 1911 when he was made a baronet, and again in 1914. Lord Leverhulme died in 1925 shortly after the final extension was completed, and the property was purchased in 1926 by Andrew Weir, first Baron Inverforth. Lord Inverforth lived at The Hill until his death in 1955, when he bequeathed the property to Manor House Hospital. The house was later renamed the house 'Inverforth House' in his memory.

The gardens and pergola were then part-purchased by London County Council, opening as the ‘Hill Garden’ in 1963, before undergoing a major renvoation project by City of London Corporation in 1986. In November 2025 the Pergola was added to Historic England's Heritage at Risk Register, which identifies it as a priority for conservation.
