.. How odd ! I posted about this the other week as I live by the Bricklayers arms and heard these mysterious sounds which woke me up at 4am on a Saturday morning. I thought it might be a Fog horn and it kept going at five minute intervals for about ten seconds at a time. I opened my bedroom window and it seemed to be coming from Bermondsey on the Tower Bridge Road
side. After several replies onto my post the sounds remain a mystery !
