Amberley Castle was originally the Manor House, built around 1200 by Ralph Luffa, the Bishop of Chichester. He also built the adjacent church but is best known for building Chichester Cathedral itself.

The castle’s fortifications were started in the 14th century by Bishop William Rede who added the Great Hall and sundry smaller buildings to the Manor House. The two towers at the entrance were part of this phase, as was most of the currently visible curtain wall. Much of the internal work from this period is now in ruins. The site remained in ecclesiastic ownership until 1578, since when it has remained in private ownership through a series of prominent local families. Currently it is a luxury hotel and restaurant.

The card, by F. Douglas Miller, shows the main approach via Castle Lane from the south. Much of the 14th century castle structure can be seen, including the two towers at the entrance and the church tower, off to the left. It was probably posted in 1918 by Aunt Helen to Miss Celia Haynes in St. John's Wood. The postmark for Paddington carries the slogan "Feed the Guns with War Bonds", no doubt reflecting some sentiment of the time.

A closer view of the main entrance between the towers is shown in the early White & Son postcard. Several of the young residents are posing for the picture, which is probably pre WW1.
