This was the first view we had of Greenwich from the Isle of Dogs on the north side of the River Thames. The obvious building is part of the Old Royal Naval College with the greenery of Greenwich Park at the back.

Maritime Greenwich was inscribed as a World Heritage Site by the United Nations Educational, Scientific and Cultural Organisation (UNESCO).

The Greenwich Foot Tunnel was opened in 1902 and was built so that local people could cross the river to the Isle of Dogs to work.

The tunnel, which is open 24 hours a day, is 1,217 feet long and runs about 50 feet under the River Thames. At each end of the tunnel there are 112 steps but there is also a lift which is open from 7am until 7pm Monday to Saturday and 10am to 5.30pm on Sunday.

The tunnel shafts have a fairly distinctive little building on the top with a single doorway giving access to both the steps and the lifts. The nearest stations are 'Island Gardens' on the Isle of Dogs (North side) and 'Greenwich Cutty Sark' on the Greenwich side (South side) both on the Docklands Light Railway.

You can't say you've 'done' Greenwich until you've walked under the Thames.

This is part of the Old Royal Naval College which was built on the site of the Tudor Palace in which Henry VIII, Mary I and Elizabeth I were born.

Most of the buildings are now used by the University of Greenwich and Trinity College of Music but some parts are open to the public and entrance is free.
