Church of St John the Baptist, Bristol

The clock-tower and spire of this 14th-century Anglican church, soar above the city's last remaining ancient gate, through which you can pass into the heart of modern Bristol. The smallest of the city's old churches, it's rarely open but even from the outside it is a remarkable sight, its nave being contained within the thickness of the medieval wall. This gate is a poignant reminder of the centuries of history that have flowed beneath its span - it was through this gate that the seven Protestant martyrs passed, as they went to their execution on Highbury Hill. King Henry VII also passed through here, as did Queen Elizabeth I in August 1574.
