The only one of the famous old mansions recently remaining was Shaftesbury or Thanet House. It was built by Inigo Jones for the Tuftons, Earls of Thanet, and was purchased by Anthony Ashley Cooper, Earl of Shaftesbury, the Achitophel of Dryden. Pennant says: "It was hired or purchased by the incendiary statesman, Lord Shaftesbury, for the purpose of living in the City to inflame the minds of the citizens, among whom he used to boast he could raise 10,000 brisk boys by the holding up of his finger. He attempted to get into the magistracy, but being disappointed in his views and terrified at the apprehension of the detection of a conspiracy he had entered into against his prince, he fled, in 1683, into Holland, where he soon died of the gout, heightened by rage and frustrated ambition." The house was afterwards let for manufacturing purposes; in 1750 it became a Lying-in-Hospital, which was removed to the City Road, when it was opened as a Dispensary, with a Dissenting Chapel, called Shaftesbury Chapel, on the first floor, until the migration of the congregation to a new chapel opposite Westmoreland Buildings, called Aldersgate Chapel. Petre, Dorchester, or London House stood on the west side of the street nearly opposite Shaftesbury House. It is supposed to have been built by Sir William Petre, who became rich by monastic plunder at the dissolution of monasteries, and died in 1572. It was occupied by his descendants until 1639, when it came into possession of Henry Pierrepoint, Marquis of Dorchester. During the Commonwealth it was made use of as a state prison, and after the Great Fire of 1666 had destroyed the palace of the Bishop of London, in St. Paul's Churchyard, became the episcopal residence of the see, many alterations being made, and the chapel built by various bishops, and was held by them until 1725. In 1748 it was occupied by Jacob Ilive, "the crazy printer and fanatical writer," and twenty years after by Seddon, the eminent cabinetmaker, ancestors of the Seddons of Gray's Inn Road, who had the misfortune to have it burnt, with the whole of his uninsured stock, on two occasions. Afterwards, also, Miss Seddon was burnt to death in the house, by her clothes catching fire.
