The Hop Farm - site of the World's largest group of Oast houses and granaries. The buildings now form a museum which is part of the wider Hop Farm visitor attraction. They were built for Whitbread in the late 19th century. The complex consists of Guests Oast, the oldest of all the oasts, named after Henry Guest the chief hop drier. It was here that various drying techniques were carried out. Temporary platforms were built to store the pokes containing green hops. In 1945-7 they were replaced with permanent gantries. The theatrical stage for entertaining hop pickers had to be removed in 1945 to make way for a permanent poke storage gantry. A marquee tent was erected to continue the entertainments. The church and writing room, now an office was situated at the west end of Bell 1. Hoppers accommodations consisted of 10 blocks of 2 storey buildings. Bell tents were used to accommodate the remaining hoppers, but were gradually replaced with blocks of single storey huts having 15 rooms back to back. Grade II* listed building.
