London is the capital and largest city of England and the United Kingdom. The city stands on the River Thames in the south-east of England, at the head of its 50-mile (80 km) estuary leading to the North Sea. The City of London, London's ancient core and financial centre − an area of just 1.12 square miles (2.9 km2) and colloquially known as the Square Mile − retains boundaries that closely follow its medieval limits.

Mallorca or Majorca is the largest island in the Balearic Islands, which are part of Spain and located in the Mediterranean. The local language, as on the rest of the Balearic Islands, is Catalan, which is co-official with Spanish.
