Roam through Roman London

London began life almost 2000 years ago as a Roman settlement and captivating clues to its origins can be discovered for free on a self-guided walking tour. The city was established on the north bank of the Thames surrounded by heavily fortified walls, and would have occupied roughly the same area as the Square Mile does today.

Spectacular segments of those original walls can be seen at Tower Hill, and they continue north along the London Wall thoroughfare, west through the iconic Barbican estate (barbecana is Latin for ‘fortification’) and into Noble Street. From there, the Guildhall Art Gallery is a short walk to the east, where you can see the impressively preserved ruins of a Roman amphitheatre.

More bang for your buck: Forgo the traditional art galleries and check out the impressive (and free) street art that covers much of Shoreditch in East London.
