There are a number of notable buildings in and around Aspley Guise. One worth mentioning is “The Rookery”. Although it is now a private home, during World War 2 this secluded Victorian mansion was the home of Australian Dennis Delmer. He was involved in “black ops” which included broadcasting radio propaganda and programmes to Germany which, among other things, suggested that Hitler had Jewish ancestry.

In fact there was much covert activity in and around Aspley Guise during the war with Bletchley Park, the home of the World War 2 Enigma code crackers, only a few minutes down the road.

Another notable house in the area is Aspley House. This is a splendid property set in grounds near the entrance to the village. It was built around 1650 and remains the largest house in the village.
