Newcastle-upon-Tyne Castle (Newcastle-upon-Tyne)
Newcastle-upon-Tyne Castle is an impressive survival in the major North Eastern city of Newcastle-upon-Tyne.
There was a Roman fort here, named Pons Aelius, and the first bridge over the River Tyne was built by Hadrian.
The "new castle" was built in 1080 by Robert Curthose, for his father William I, and this was rebuilt by Henry II in 1272, featuring a strong keep with walls 15 feet thick.
The Black Gate, originally a barbican, was added in 1247.
During the Civil War the Scots captured Newcastle but the castle held out for a further three days.
Today the keep, the Black Gate and a section of curtain wall remain.
