The image is a blue plaque on a stone wall with ivy growing around it. The plaque is rectangular in shape and has a white background. On the top of the plaque, there is a coat of arms with a shield and a crown on top. Below the shield, it reads "The House in the Rock was partly excavated from the crag by a linen weaver, Thomas Hill, and his son between 1770 and 1791. Originally known as Fort Montague, it was a popular tourist attraction but became a purely private residence in 2000." The plaque also has the words "Knaresborough Civic Society 2007" written on it.
