 There has been a resident Treasury or Downing Street cat employed as a mouser and pet since the reign of Henry VIII, when Cardinal Wolsey placed his cat by his side while acting in his judicial capacity as Lord Chancellor, an office he assumed in 1515.
The 10 Downing Street Guard Chairs are two antique chairs.
 In the early 19th century, 10 Downing Street was guarded by two men who sat outside the building in leather chairs made by Thomas Chippendale.
 There was a drawer underneath the chair which was filled with hot coals to keep the guards warm whilst on duty.
 The chairs were made with a circular back and hood, both to shield the guards from bad weather and to improve the surrounding acoustics, thereby allowing the guard to hear better from a wider angle.

The Downing Street mortar attack was carried out by the Provisional Irish Republican Army (IRA) on 7 February 1991.
 The IRA launched homemade mortar shells at 10 Downing Street, London, the official residence of the Prime Minister of the United Kingdom.
 It was an attempt to assassinate Prime Minister John Major and his War Cabinet, who were meeting to discuss the Gulf War.
 One of the heavy mortar shells exploded in the back garden of number 10, only yards from the cabinet office.
 Due to the bomb-proof windows, none of the cabinet were hurt, though four other people received minor injuries, including two police officers.
 The other two shells overshot Downing Street and landed on a green nearby.
