It seems very surprizing that so great a piece of antiquity has been constantly preserved with such care, and yet so little has been said of it, that the original cause of its erection, and the use for which it was intended, are entirely unknown. A very ingenious author observes, that as London appears to have been a Roman city, it will be no improbable conjecture, that this stone was the center, from whence they extended its dimensions, and might serve as the standard at which they began to compute their miles. Of this opinion was also Mr. Maitland, and the great Sir Christopher Wren, who grounded his conjecture upon proofs which are not every day to be obtained, for by rebuilding many of the churches after the fire of London, he had an opportunity of discovering and tracing the ancient boundaries of London, with a greater nicety than is ever to be expected again: on clearing the foundations of St. Mary le Bow in Cheapside, he found, upon opening the ground, the walls with the windows and pavement of a Roman temple, entirely buried under the level of the present street; this temple stood about forty feet backwards; but having occasion to bring the steeple of the new church to range with the high street, he again began to dig through the made ground, till having proceeded eighteen feet deep, to his surprize he discovered a Roman causeway of rough stone four feet thick, close and well rammed, with Roman brick and rubbish at the bottom, all firmly cemented; he was therefore of opinion, that this was the northern boundary of the Roman colony, and that the breadth from north to south was from this causeway, now Cheapside, to the Thames; the extent east and west from Tower hill to Ludgate: the principal or Prætorian Way, he supposed to be Watling street; whence London Stone appears to have been nearly in the center of the ancient city before it was destroyed by Boadicea, and when it was not encompassed with walls. _Curiosities of London and Westminster._ _Parentalia._ LONDON _street_, 1. A spacious, handsome, and well-built street, on the south side of Fenchurch street. 2. Mill street, Rotherhith. 3. Rose lane, Ratcliff. LONDON WALL, the wall which formerly surrounded the city of London, as a defence against the attacks of an enemy. It was strengthened with lofty towers, and had originally only four gates, tho’ the making of new roads has increased the number to seven, which are now standing, viz. Aldgate, Bishopsgate, Moorgate, Cripplegate, Aldersgate, Newgate, and Ludgate. See each of these described in their proper places.
