Alhambra (889 AD)
A Spanish Palace with Enormous Global Impact
The Alhambra is a palace and fortress situated in Granada, Spain. The building was initially constructed as a small fortress in 889 and was rebuilt in the mid-11th century by its founder, Mohammed Al-Ahmar. His son Muhammed II, who continued updating the fortress, completed his work. Yusuf I, Sultan of Granada, converted the building into a royal palace in the 14th century. The Alhambra is a fantastic example of cultural diplomacy because it represents a reflection of the Moorish culture in Spain. The Moors ruled parts of Andalucía for 800 years until the late 15th century and this beautiful monument exemplifies their legacy. Alhambra has had a huge global impact. Whilst international songs and books have been written about this fascinating palace, its architecture and design has been mathematically stimulating as the building contains nearly all of the seventeen mathematically possible wallpaper groups that are complexly symmetrical. In recognition of this importance, it became a UNESCO World Heritage Site in 1984.
