St. Paul's Cathedral

Beginning at St Paul's, cross over Ludgate Hill and head east. St. Paul's was built by Christopher Wren in response to the previous St. Paul's (the fourth such building on the site) being destroyed in the Great Fire of London (1666). It took 31 years to complete the building, built entirely of costly but durable Portland stone. Despite the entire surrounding area being destroyed by bombs during the Second World War, the cathedral miraculously survived many near-misses. Wren was the first person to be interred after his death with the epitaph (translated from the Latin) - "Reader, if you seek his monument, look around you." The entrance to Millennium footbridge can be found to the south of the cathedral

Millennium Bridge

Cross over the foot bridge, the newest of the Thames bridges, which opened and closed in quick succession in June 2000. Nicknamed the 'wobbly bridge' it required further damping, which fixed the problem and subsequently it reopened early the next year. The large brick building on the far side is Bankside Power Station - home of the Tate Modern.

Tate Modern

Take a left on the south bank of the Thames, heading east. This route is part of the Thames Path, which starts in Kemble in the Cotswolds and stretches to the Thames Barrier at Charlton (184 miles). There are numerous points of interest en route, including The Golden Hinde, Borough Market, HMS Belfast and Shakespeare's Globe, before arriving at.

Hay's Galleria

A converted mid-Victorian covered wharf, containing shops, restaurants and offices. It also houses an acclaimed, moving bronze sculpture - The Navigators, by David Kemp. Continue east to City Hall, the seat of London's Mayor and take in the 'scoop' a sunken amphitheatre where free concerts are staged during the summer. You also can't fail to have noticed.

Tower Bridge

After a few obligatory photos of the bridge, cross it via the walkways which run along the road (the steps leading up to it are clearly signposted). if you're lucky you might have to wait while a ship passes underneath (this happens several times a day on average). On the other side you will no doubt be aware of the.

Tower of London.

Built by William the Conqueror in 1078, descend the steps at the end of Tower Bridge and start walking along the Thames Path on the north side, heading west. The entrance to the Tower is via the West Gate. The castle is home to 10 resident ravens, who live on site and are cared for by the Ravenmaster (yeoman). The suspicion that the kingdom would fall if the ravens left the site, was nearly put to the test when only one (named 'Grip') survived the countless bombing raids of World War 2 (the others died from shockwaves). Fresh ravens were introduced in 1946.
