The Guildhall complex is London's oldest city hall. It rises in the Square Mile where the first urban nucleus developed from the Roman foundation to the middle of the first century AD.
Various noteworthy rooms of different capacities for entertainment, dinners and shows can be visited: The Great Hall 900 seats, the Old Library and Print Room 500/600 seats, East and West Crypts 500 seats, the Livery Hall 330 seats, Basinghall Suite 100 seats, Chief Commoner's Parlor 24 seats and the Art Gallery 330 people.
The latter, already present at the end of the 1800s, was destroyed during the Second World War, and then rebuilt in 1985 and inaugurated in 1999. At the beginning of the works, the Roman amphitheater was discovered underground, which has been open to the public since 2002 .
The entrance to the Gallery is free, there are Victorian works from various periods and others representing events and city life from the 17th century.
