Charles and Camilla’s groundbreaking trip is likely to usher in a new chapter in the relationship between the UK and the Communist state once ruled by Fidel Castro.
The Queen is, unsurprisingly, the most well-travelled of the royal family, having paid official visits to more than 100 countries during her time on the throne.
Her reign began on foreign soil after her father George VI died while she was staying in Kenya.
There are a number of countries and territories which the Queen has not visited, including some former members of the Soviet Bloc.
In contrast, vast swathes of the South Pacific have been covered by royal visits from the Queen such as Nauru, Kiribati, Tuvalu and Fiji on board the Royal Yacht Britannia.

Many Commonwealth members have received the British head of state or a representative, but many other African countries have not, including Mali in the west and Djibouti in the east.
A number of Asian countries are also awaiting their first glimpse of British royalty, including North Korea.
