Southwark (/ˈsʌðərk/ SUDH-ərk)[1] is the main part of the inner London Borough of Southwark. It is on the Thames, south of London Bridge. It is often called just 'The Borough'. Southwark was once a separate town in Surrey, and was made part of London in 1889.
Southwark has several important buildings: Southwark Cathedral, London Bridge station and the Tate Modern art gallery. Two Roman roads met in Southwark: Watling Street and Stane Street. The area was marshy with islands in Roman times. They built the first London Bridge here.
The word 'Southwark' is pronounced Suthuk.
