Old churches

Is there a website where I can look for old demolished Churches? My son sent me a photo of St.Andrews in New Kent Road but I can't for the life of me remember where it was..I remember very well the old St Matthews church because my Auntie used to hold Jumbles and Fetes there.

I know you wise folks will be able to steer me in the right direction..:-)

Sons just phoned me to remind me..on the site of the Petrol Station, I remember now the small part that remained was turned into a camping place, I used to collect calor gas canisters from there in the early 80's..

There is indeed a site for Southwark: http://www.southwark.anglican.org/where/lost-churches
