St John's Gate, Clerkenwell

St John's Gate, in Clerkenwell, Middlesex, now within central London, is one of the few tangible remains from Clerkenwell's monastic past. It was built in 1504 by Prior Thomas Docwra as the south entrance to the inner precinct of Clerkenwell Priory, the English headquarters of the Knights of the Order of St John (known as the Knights Hospitaller).

The substructure is of brick, while the north and south façades are of stone. After centuries of decay and much rebuilding, very little of the stone facing is original. Heavily restored in the 19th century, the Gate today is in large part a Victorian recreation, the handiwork of a succession of architects—William Pettit Griffith, R. Norman Shaw, and J. Oldrid Scott.
