Early Roman London was scarcely larger than Hyde Park. Mr. Roach Smith, the best of all authorities on the subject, gives its length from the Tower to Ludgate, east and west, at about a mile; and north and south, that is from London Wall to the Thames, at about half a mile. The earliest Roman city was even smaller, for Roman sepulchres have been found in Bow Lane, Moorgate Street, Bishopsgate Within, which must at that time have been beyond the walls. The Roman cemeteries of Smithfield, St. Paul's, Whitechapel, the Minories, and Spitalfields, are of later dates, and are in all cases beyond the old line of circumvallation, according to the sound Roman custom fixed by law. The earlier London Mr. Roach Smith describes as an irregular space, the five main gates corresponding with Bridgegate, Ludgate, Bishopsgate, Aldersgate, and Aldgate. The north wall followed for some part the course of Cornhill and Leadenhall Street; the eastern Billiter Street and Mark Lane; the southern Thames Street; and the western the east side of Walbrook. Of the larger Roman wall, there were within the memory of man huge, shapeless masses, with trees growing upon them, opposite what is now Finsbury Circus. In 1852 a piece of Roman wall on Tower Hill was rescued from the improvers, and built into some stables and outhouses; but not before a careful sketch had been effected by the late Mr. Fairholt, one of the best of our antiquarian draughtsmen. The later Roman London was in general outline the same in shape and size as the London of the Saxons and Normans. The newer walls Pennant calculates at 3 miles 165 feet in circumference, they were 22 feet high, and guarded with forty lofty towers. At the end of the last century large portions of the old Roman wall were traceable in many places, but time has devoured almost the last morsels of that great _piece de resistance_. In 1763 Mr. Gough made a drawing of a square Roman tower (one of three) then standing in Houndsditch. It was built in alternate layers of massive square stones and red tiles. The old loophole for the sentinel had been enlarged into a square latticed window. In 1857, while digging foundations for houses on the north-east side of Aldermanbury Postern, the workmen came on a portion of the Roman wall strengthened by blind arches. All that now substantially remains of the old fortification is a bastion in St. Giles's Church, Cripplegate; a fragment in St. Martin's Court, off Ludgate Hill; another portion exists in the Old Bailey, concealed behind houses; and a fourth, near George Street, Tower Hill. Portions of the wall have, however, been also broached in Falcon Square (one of which we have engraved), Bush Lane, Scott's Yard, and Cornhill, and others built in cellars and warehouses from opposite the Tower and Cripplegate.
