The two priest holes within the building, used during the 16th and 17th centuries to conceal Catholic clergy, are located in the east wing in a void under the turret, and in the south wing behind a chimney stack in the old study. In the 20th century, when Lady Rasch, widow of the 16th Baron Petre, moved the family back to Ingatestone Hall, she began a major project to restore Ingatestone Hall to its original Tudor appearance. The works, overseen by the architect, W.T. Wood, included replacing alterations to the building with reproductions of Tudor period features, notably the re-instatement of mullioned windows on the west side of the building on the ground floor. The initial phase of project was completed in 1922. In literature and film Mary Elizabeth Braddon's 1862 novel Lady Audley's Secret is set at Ingatestone Hall and was inspired by a stay there. The exterior of hall was used as a filming location to represent Bleak House in the 2005 television adaptation of Charles Dickens' novel and also appeared in an episode of the TV series Lovejoy. Sketches from the TV programmes Horrible Histories and The Fast Show were also filmed at the hall.
