Cliveden

National Trust
The house, built in 1850-1, is the third on the site, the two previous ones having burnt down. It is now a hotel, which you can visit at any time as a guest if you are wealthy. Otherwise, visiting is restricted to three rooms for 2 1/2 hours twice a week.
The extensive and spectacular gardens and grounds are open daily to NT visitors. Notable features are the large Parterre, which offers the best view of the house, the Fountain of Love, the steep drop to the Thames which borders the gardens to the north, and the Water Garden. If your legs are tired, check out the cinema next to the main car park for an interesting film about the house and its occupants.
In March 2012 some works were being carried out below the house terrace to improve drainage. (visited March 2012)
