Logo
Known as the Bridge Mark, the logo of Bridge House Estates was one of the earliest logos ever in continuous use and can be found carved into stonework in many places along the riverfront. It has been the identifying emblem of the Bridge House Estates for many centuries. but it now uses the City of London arms as an emblem. The City Bridge Trust uses the mark as a logo
It was thought likely that the mark as we know it today was designed by a famous 17th century surveyor, William Leybourn, drawn on a plan of 1680 which it is thought he adapted from a similar mark drawn against plots owned by Bridge House Estates on an earlier plan of St George's Fields in Southwark. However, an earlier date on the City sword rest from the church of St Olave, Southwark (now in the north transept of Southwark Cathedral) has a carved date of 1674 and has the Bridge Mark carved onto it to balance the City's shield.
