twb[23] - leading lights {2 of 4}

A word of explanation. The term "Leading Lights" refers to a navigational aid for entering a channel or harbour; these are a pair of marks that, when aligned vertically mean that you are lined up with the safe route.

In the case of the River Tyne, a general description of these are a pair of white painted towers, the bottom one on the lower quays and the other up on the headland above.

This image is of the "New High Light" which was built on Dockwray Square - as a "light" the lantern was in use from 1810 to 1999, but the building is still used as a "day mark".
