The is the High Street side of Brasnose College, the south side, one of the (currently) 39 colleges which together comprise Oxford University in England.  The university's roots are said to date from the year 1096, with this college being founded in 1509.  It is thought to have been named for a brass or bronze door knocker.  Michael Palin is among its better known alumni, along with the recent PM, David Cameron.  The east side of the college faces both the famous, cylindrical Radcliffe Camera and the University Church of Saint Mary the Virgin, which is visible at the right in my photograph.  The detail in this one is so great that a print could still be sharp at about 14 feet wide.
