This gateway is a remnant of the New Gaol, which is apparently sometimes called The Old City Gaol, oddly. I suppose it depends on one's historical perspective.
The original New Gaol was destroyed during the 1831 Bristol Riots, and replaced with a redesigned version including this gate. That replacement New Gaol was itself replaced by Horfield Prison (which still stands and still operates as a prison) in 1884 and demolished in 1898. So, in fact, you could argue that this the ex-old-new-New Gaol. Clear? Good.
