The wealth of the cultural heritage in Spain is immense. Throughout the millennia this land has seen the development and demise of many cultures, each leaving unique artworks and structures. The most amazing wonders of Spain are:

  • Medieval cities. Only Italy can compete (and possibly is winning) in the wealth and diversity of urban heritage.
  • Churches. Spain has the largest Gothic church in the world (Seville Cathedral) and the tallest church (Sagrada Familia). Unique are churches that serve as a link between Roman and Western European architecture traditions, such as Santa María de Melque Church.
  • Moorish castles and palaces. The Moorish palaces of Spain belong to the most beautiful palaces in the world, some of the best are Alhambra, Aljafería, and Generalife palaces.
  • Cave art. Hundreds of caves in Northern Spain (also other regions of the country) are adorned with prehistoric paintings and engravings, often made with great artistic talent.

Spain is divided into 17 autonomous communities and 2 autonomous cities. One of autonomous communities – Canary Islands – is described in its own page.
