According to SE1 Forums... "Interestingly www.southlondonguide.co.uk/walworth/history.htm says that part of Penton Place was built over part of the old Surrey Gardens Music Hall in 1873, but this site: http://www.arthurlloyd.co.uk/Surreyhall.htm shows that Penton Place did exist in part beforehand as there was an entrance to the hall when it existed"
