An inscribed block of Caen stone is incorporated into the interior of the porch on the north-west side of Mansion House (1030450). The stone reads:
TAVS * 35
1543 Henry VIII, 35th year of his reign
The stone was drawn at a scale of 1:1 by RCHME as part of the archaeological survey of Nonsuch Park carried out between 1993 and 1995.
