If there is one site that offers an in-depth journey into the Islamic history of Spain, it would have to be the Alhambra, Generalife, and Albazyin. The Alhambra is a palace and fortress complex originally constructed in 889 AD. Adjacent to the Alhambra, Generalife features beautifully manicured gardens. The Alhambra and Generalife were inscribed as UNESCO World Heritage Sites in 1984. However, the boundaries were later altered in 1994 to include Albayzin. Albayzin is a historic district of Granada, featuring the medieval Moorish quarter with narrow winding streets and whitewashed houses.

UNESCO recognized the Alhambra and the Generalife for their stunning Islamic architecture, historical significance, and exceptional preservation of medieval Islamic art and culture. The Albayzín was added for its historical value as the original Arab district of Granada, offering insights into medieval Islamic urbanism.

Make sure you purchase your tickets well in advance as entry to the Alhambra is limited to preserve it. Consider having guided tours for deeper insights into its rich architectural styles and history. If you decide to explore it alone, do not miss out on Nasrid Palaces and the Palace of Charles V. On the Generalife Gardens, take a keen interest in Patio de la Acequia, the most famous courtyard featuring a long pool framed by flowerbeds, fountains, colonnades, and pavilions.

Some noteworthy highlights of the Albayzín include the Mirador de San Nicolás, a viewpoint offering stunning views of the Alhambra against the backdrop of the Sierra Nevada mountains, and El Bañuelo, one of the best-preserved Arab baths in Spain. For an in-depth trip, spare at least 6 hours.

Works of Antoni Gaudí, Barcelona

Gaudi was iconic. We would love to recognize his architectural masterpieces independently on this list. However, UNESCO jointly recognizes seven of his works as “Works of Antoni Gaudi.” The seven recognized works, located in and near Barcelona, include Parque Güell, Casa Mila, Palacio Güell, Casa Vicens, the Crypt in Colonia Güell, Nativity façade and Crypt of La Sagrada Familia, and Casa Batlló.

While La Sagrada Familia is recognized as Gaudi’s most popular and ambitious project, his other works are equally impressive. Visiting these sites lets you explore his unique style, which blends neo-Gothic art with Art Nouveau. If you are an architecture buff, you will love exploring the intricate designs, organic shapes, vibrant colors, and mosaic features of his works.

Have little time in Barcelona? Prioritize the works of Gaudi; this would still be a decent enough trip to Barcelona.
