sentences:  The deanery was demolished and its place abutting the gatehouse was taken by the new Bristol Central Library building in 1906.The building consists of two late Norman archways, a carriage gateway and a smaller postern gate for pedestrians, surmounted by a late Perpendicular gatehouse, with an adjoining tower.The unweathered appearance of the archways led to a public debate between 19th century commentators as to whether the archways had been rebuilt since the 12th century, but the prevailing view, as argued in the 19th century by George Edmund Street, is that they are probably the original ones.
