The old palace, burnt down in the Great Fire, was built round two courtyards; in its later days rebuilt, it followed the frequent fate of such ancient monuments, and became partly a “hospital” for poor boys, partly a prison for vagrants and other unwanted persons. It was also a hospital for lunatics, and was put under the same management as Bethlehem in 1557. Bridewell is also fully described in _London in the Eighteenth Century_. The part of London bounded north and south by Fleet Street and the River, east and west by New Bridge Street and the Temple, is now almost entirely occupied by mammoth printing-offices; yet on the Embankment are one or two buildings of note: Sion College, opened here in 1886 to supersede the old building on London Wall; the Guildhall School of Music; the City of London School for Girls (all modern). After Blackfriars Bridge, running behind the line of wharves and warehouses, begins Thames Street, Upper and Lower, once one of the principal thoroughfares in London, a London that knew nothing of what is now called the “West End.” It is now a noisy street “pestered” with drays and vans, with cranes and their accompaniments, so that to walk therein in work-hours is a perilous proceeding. Yet this ancient street, Thames Street, is, not even excepting West Chepe, the most interesting and the most venerable of all the streets of London. It is the seat of the export and the import trade. From Thames Street the City sent abroad the products of the country—the iron, the wool, the skins and hides; from Thames Street the City distributed the imports to the various parts of the country. Off the wharves of Thames Street lay the shops of all the nations of Western Europe. In the narrow lanes leading down to the stairs between the quays lived the seafaring folk and those who worked for them, and those who worked for the merchants. London at one time was roughly divided into belts of population. The first belt is that of the Service. It consists of the foreshore between Thames Street and the river, with the lanes and houses upon it. The second is that of the Merchants, between Thames Street and the Markets of West and East Chepe. The third is that of the Markets. The fourth that of the Industries between the Markets and the Wall. As to the first: The Wall of London, when it was first erected, was carried along the river from the south-west angle to the Walbrook. Beyond the Walbrook the south wall of the Roman fortress formed a river-wall, which was continued as far as the south-east angle. Beyond that stream the south wall of the Roman fort was allowed to remain as the river-side wall of the City, when all the rest of the Roman buildings, temples, public edifices, tombs, and villas were ruthlessly pulled down to build the wall towards the end of the fourth century.
