Roman London (Londinium)
Dig under the City and you hit a layer of red ash: Boudica's rebels burned this whole town to the ground in AD 60/61.

Founded around AD 47-50 on virgin ground, Londinium grew to 30,000-60,000 people and left ruins you can still touch: a defensive wall that survived 1,600 years and roughly traces the City's edge today, plus a temple, an amphitheatre, and a basilica once the largest north of the Alps.
What to look for
- The amphitheatre remains (built AD 70) below the Guildhall Art Gallery
- Open-air sections of the wall, originally ~6 m high and ~2.5 m thick, at Tower Hill, 8-10 Coopers Row and St Alphege Gardens, plus the fort's southwestern tower at Noble Street
- The London Mithraeum, a temple of about AD 240, reassembled beneath the Bloomberg building
Wall fragments cluster along a short walk near Tower Hill tube; major mosaics and finds sit at the Museum of London.
