For WW2 Reigate was chosen as General Montgomery's South Eastern Command HQ,(probably by Churchill), tucked under the hill along the Pilgrim's Way and out of sight, with magnificent views to the south. A local resident describes why it was called Moss's Place - after the father of Stirling Moss, the famous racing driver who lived there all that time.
It now emerges that in WW2, Winston Churchill sometimes stayed at another large house just five minutes walk - just along the Pilgrim's Way, to write his speeches as a secret and secure refuge in the countryside out of London. He visited Reigate over several decades on social, business and secret political and royal missions.
Churchill most likely flew over it too, from Biggin Hill aerodrome.
He noted in his diary the comfort of Reigate Priory and added his signature to the official guest book on several occasions. He was always fond of uplifting vistas and sunlight for health and wellbeing, around the world, and acknowledged that it was good for health.
