Blackfriars Bridge is a bridge in London that sits over the River Thames. It was constructed in the 1700's and still stands as of today. In Daniel Deronda, this was the place where Daniel became more understanding of Mordecai and his belief of souls being changed into another form. The reason that they are here at the bridge is because this was how Mordecai saw his spiritual heir rising out of the sunset in his vision. In the novel when this is taking place, this is Mordecai's way of permitting Daniel to approach Mordecai by water.
Due to the high demand of traffic, this bridge was widened in the early 1900's to allow for more traffic to flow through. The bridge holds stone carvings on the piers of water birds, as well as a statue of Queen Victoria, which happened to be who the bridge was dedicated too. The bridge gets the name "Blackfriars" due to the ends of it being shaped like a pulprit.
