London Barbican Centre: A wonderful combination of modernity and history.

Barbican Centre is located in the heart of London's financial district and is a large complex of buildings. Here, a series of London's oldest city walls are also preserved, which were built within the original boundary of the walled city. The architectural style is rough and connected with the surrounding churches and schools, with a grayish color that is very distinctive. Inside the Barbican Centre, there are theaters, art galleries, and libraries. It's huge and easy to get lost. It's nice to stroll around the ancient city walls outside, but the entrance is hard to find.
