London City Hall | Encounter with the ancient Roman Colosseum

Guildhall, located in the City of London, is partially open to the public and a great place to learn about London's history. The Guildhall Art Gallery showcases the city's history through its painting exhibitions, and admission is free! The most impressive thing is the Roman ruins under the art museum: the underground exhibition hall has excavated remains of the ancient Roman amphitheater, although it is in ruins, it is also the most intuitive memory of London's history. The initial location of ancient Rome's city building, as well as one of the busiest places in London today, can be called the essence of history.
