Salomons purchased Norbury Park near Mickleham in Surrey from the estate of Sir Thomas Grissell in 1890. In 1914 he purchased 230 acres of Box Hill to protect it from development, which he subsequently donated to the nation. A memorial to Salomons (commonly known as The Viewpoint) was constructed at the summit of the hill and was opened by his widow in 1920. Box Hill became the UK's first Country Park and is now owned and managed by the National Trust.
