Downing Street declined at the turn of the 19th century surrounded with run-down buildings, dark alleys, crime and prostitution. Earlier, the government had taken over the other Downing Street houses: the Colonial Office occupied Number 14 in 1798: the Foreign Office was at Number 16 and the houses on either side; the West India Department was in Number 18 and the Tithe Commissioners in Number 20. The houses deteriorated from neglect, became unsafe, and one by one were torn down. By 1857, Downing Street's town houses were all gone except for Number 10, Number 11 (customarily the Chancellor of the Exchequer's residence) and Number 12
