Historic architecture
The City of London is the place from which the capital grew - so it's no surprise that you'll find some of London's most historic buildings here. As you wander around you're likely to see bits of Roman Wall and you can even visit the remains of London's Roman Amphitheatre. Don't miss seeing the majestic trio of the Mansion House, Royal Exchange and the Bank of England at Bank junction - and be sure to pay a visit to the Gothic-looking Guildhall (guided tours take place each month).
