24 of these cathedrals have been declared UNESCO World Heritage Sites, either by themselves, like Burgos, or as part of a larger site, generally including the surrounding old town area, as is the case with San Cristóbal de La Laguna or Ibiza.
Twenty-four cathedrals are part of the UNESCO World Heritage Sites list; some, like Burgos, stand alone, while others, including San Cristóbal de La Laguna and Ibiza, are included in larger sites that also feature their surrounding old town areas.
