The Tower of London is situated at the south-east end of the city, on the river Thames, and consists in reality of a great number of towers or forts, built at several times, which still retain their several names, though at present most of them, together with a little town and church, are enclosed within one wall and ditch, and compose but one entire fortress. It was the vulgar opinion that the Tower was built by Julius Cæsar; but, as I have before shown, history informs us that Cæsar made no stay in England, that he erected no town or fortress, unless that with which he enclosed his ships on the coast of Kent, nor left a single garrison or soldier in the island on his departure. This Tower, as now encompassed, stands upon twelve acres of ground, and something more, being of an irregular form, but approaching near to that of an oblong, one of the longest sides lying next the river, from whence it rises gradually towards the north, by a pretty deep ascent, to the armoury, which stands upon the highest ground in the Tower, overlooking the White Tower built by William the Conqueror, and the remains of the castle below it on the Thames side, said to be built by William Rufus. As to the strength of the place, the works being all antique, would not be able to hold out four-and-twenty hours against an army prepared for a siege: the ditch indeed is of a great depth, and upwards of a hundred feet broad, into which the water of the Thames may be introduced at pleasure; but I question whether the walls on the inside would bear the firing of their own guns: certain it is, two or three battering-pieces would soon lay them even with the ground, though, after all, the ditch alone is sufficient to defend it against a sudden assault. There are several small towers upon the walls; those of the largest dimensions, and which appear the most formidable, are the Divelin Tower, on the north-west; and the Martin Tower on the north-east; and St. Thomas’s Tower on the river by Traitor’s Bridge; which I take to be part of the castle said to be built by William Rufus. There is also a large tower on the outside the ditch, called the Lions’ Tower, on the south-west corner, near which is the principal gate and bridge by which coaches and carriages enter the Tower; and there are two posterns with bridges over the ditch to the wharf on the Thames side, one whereof is called Traitor’s Bridge, under which state prisoners used to enter the Tower. The principal places and buildings within the Tower, are (1) The parochial church of St. Peter (for the Tower is a parish of itself, in which are fifty houses and upwards, inhabited by the governor, deputy-governor, warders, and other officers belonging to the fortress).
