Most beautiful palace
Palaces are built to boast wealth and magnificence, so it's no wonder we had contenders galore. St Petersburg, Versailles, the Potala Palace, the Forbidden City... the list goes on and on.

Built by the Moorish rulers of the emirate of Granada in the 14th century, it is a masterpiece of Islamic design and decorative embellishment, reflecting its history as a refuge for artists and intellectuals.
