This is a plan of the St Paul's Cathedral in London, England. It is an example of English Renaissance architecture. The construction lasted from 1675 to 1710. Sir Christopher Wren designed the cathedral. "In plan, Wren's design was in accordance with the traditional arrangement of an English cathedral, with nave, north and south transepts and choir, in all the cases with side aisles together...Wren introduced a series of cupolas over the main arms of the cathedral, which enabled him to light with clerestory windows; these are not visible on the exterior, as they are masked by the upper storey which Wren carried round the whole structure, in order, probably, to give it greater height and importance." The scale is given in feet.
