World's End And Tilbury Fort Walking Along The Thames Estuary With Yorkie Lucy

Tilbury Fort on the Thames estuary protected London’s seaward approach from the 16th century through to the Second World War.
Henry VIII built the first fort here, and Queen Elizabeth I famously rallied her army nearby to face the threat of the Armada. The present fort is the best example of its type in England, with its circuit of moats and bastioned outworks.
