Goswell Road, in Central London, is an end part of the A1. The southern part ends with one block, on the east side, in City of London; the rest is in the London Borough of Islington, the north end being Angel. It crosses Old Street/Clerkenwell Road. In the north it splits Clerkenwell from Finsbury;[1] the south was sometimes used as a demarcator but all but the southern corporate/legal/financial end in the modern era forms the heart of the highly developed mixed-use district Barbican.
All of the road is inside the Central London congestion charge zone.
