History The Hop Farm has been operating for over 450 years. In Victorian England, a cluster of oasthouses were built at the site, and this remains the largest gathering of such structures in the world. In the 19th century, the phrase 'Hopping Down in Kent' was coined as complete families travelled from London to Kent in September to harvest hops. This tradition continued until after World War II, city-dwellers greatly enjoying their annual vacation in the countryside. Sold by the Whitbread Brewery in 1997, then re-opened as an historic industrial centre, today The Hop Farm is one of Kent's most popular tourist attractions and family parks.
