During the Wars of the Three Kingdoms of 1644 to 1647 the city was plundered by both sides. In 1644, it was taken and ransacked by Royalist troops after the Battle of Aberdeen and two years later it was stormed by a Royalist force under the command of the Marquis of Huntly. In 1647 an outbreak of bubonic plague killed a quarter of the population. In the 18th century, a new Town Hall was built and the first social services appeared with the Infirmary at Woolmanhill in 1742 and the Lunatic Asylum in 1779. The council began major road improvements at the end of the 18th century with the main thoroughfares of George Street, King Street and Union Street all completed at the beginning of the 19th century.
