George I was buried in Hanover.
Most of the Tudor and Stuart monarchs had been buried in Henry VII's chapel at Westminster Abbey. The three exceptions were Henry VIII, Lady Jane Grey, and James II.
Henry VIII was the second monarch, after Henry VI, to be buried in St. George's Chapel, in Windsor Castle. And like most people who've been executed in the Tower of London (including Anne Boleyn, Catherine Howard, Sir Thomas More, and her own husband Lord Guilford Dudley), Queen Jane was buried in the Tower's own parish church – the Chapel Royal of St Peter ad Vincula.
James II's remains were distributed to six different places in France (five of them in Paris).
George I's son, George II, was the last monarch (to date) to be buried in Westminster Abbey (Henry VII's chapel). His grandson, George III, became the third to be buried in St. George's chapel, after which it superseded Henry VII's chapel as the burial place of choice for British monarchs. The only two monarchs since George II not to have been buried there were Queen Victoria and Edward VIII, both of whom were laid to rest on the Frogmore estate (also at Windsor).
