Of the metropolis, the City, properly so called, was the most important division. At the time of the Restoration it had been built, for the most part, of wood and plaster; the few bricks that were used were ill baked; the booths where goods were exposed to sale projected far into the streets, and were overhung by the upper stories. A few specimens of this architecture may still be seen in those districts which were not reached by the great fire. That fire had, in a few days, covered a space of little less shall a square mile with the ruins of eighty-nine churches and of thirteen thousand houses. But the City had risen again with a celerity which had excited the admiration of neighbouring countries. Unfortunately, the old lines of the streets had been to a great extent preserved; and those lines, originally traced in an age when even princesses performed their journeys on horseback, were often too narrow to allow wheeled carriages to pass each other with ease, and were therefore ill adapted for the residence of wealthy persons in an age when a coach and six was a fashionable luxury. The style of building was, however, far superior to that of the City which had perished. The ordinary material was brick, of much better quality than had formerly been used. On the sites of the ancient parish churches had arisen a multitude of new domes, towers, and spires which bore the mark of the fertile genius of Wren. In every place save one the traces of the great devastation had been completely effaced. But the crowds of workmen, the scaffolds, and the masses of hewn stone were still to be seen where the noblest of Protestant temples was slowly rising on the ruins of the Old Cathedral of Saint Paul.
