The Spanish World Heritage Cities group includes most of the cities that UNESCO has protected in Spain: Ávila, Cáceres, Córdoba, Cuenca, Salamanca, Santiago de Compostela, Segovia, Toledo, Alcalá de Henares, Ibiza and San Cristóbal de La Laguna. 

Santiago de Compostela
Santiago de Compostela, World Heritage City and capital of Galicia, is the final landmark on the St. James pilgrimage route. Centuries of splendour and development have left us an urban layout in which the medieval Christian heritage is mixed with monumental Baroque buildings. The Parador de Turismo de Santiago, right in the Plaza del Obradoiro, welcomes guests and offers them the opportunity to taste the best of the Galician culinary tradition. It is a tradition which reaches its peak during the Festival of the Apostle Saint James, declared of International Tourist Interest. 

Ibiza
A Phoenician-Punic settlement during ancient times, Ibiza contains within its Renaissance walls an interesting legacy from all the different cultures that populated it. This artistic wealth is found in the monumental area of Dalt Vila, in the necropolis of Es Puig des Molins and in the archaeological site of Sa Caleta. The beauty of the island capital is enhanced by the sands and coves at Figueretes, Es Viver and Talamanca, as well as by its the diverse marine ecosystem. 

Córdoba
Situated deep in Andalusian Autonomous Region, Cordoba is a compendium of history and modernity. This ancient city, which has been declared World Heritage Site, is a living legacy of the diverse cultures that settled in it throughout history.
Very few places in the world can boast of having been the capital of Hispania Ulterior under the Roman Empire, and the capital of the Umayyad Caliphate. Such splendour is palpable in the intellectual wealth of this centre of wisdom and knowledge, that has seen the birth of figures like Seneca, Averroes and Maimonides.

To take a stroll through the historic quarter of Cordoba is to discover a beautiful network of small streets, alleys, squares and whitewashed courtyards arranged around the Mosque-Cathedral, which reflects the importance of the city during medieval times and which is a real symbol of the capital.

Without disregarding its splendid past, Cordoba is definitely a modern city that has been able to adapt to the present day, offering the most modern infrastructures and services, as well as a large network of hotels.
Very well connected to the other Andalusian capitals, Cordoba also has the high speed train (AVE) and a very extensive railway network linking it to all the big cities, like Madrid and Seville. Once inside the city, a large network of buses and taxis enable visitors to reach any destination in a few minutes.

Cordoba is also synonymous with art, culture and leisure, thanks to a myriad of cultural events that are organised here throughout the year: Flamenco festivals, concerts, ballet and other activities that are complemented by a number of museums and an exciting nightlife.

Meanwhile, the province is home to important buildings of the Andalusian heritage, whose highest expression is the Medina Azahara, located on the outskirts of the city. But there is great spectacle also for nature lovers. The parks of Sierra de Cardeña in Los Pedroches and Montoro, the Hornachuelos Sierra and Sierras Subbéticas offer the possibility of practising all kinds of open-air sports, while at the same time enjoying the natural wealth of this province.

San Cristóbal de la Laguna
San Cristóbal de La Laguna, the former capital of Tenerife, is an historic Canary Islands city with a long university tradition. Its model colonial layout, awarded World Heritage status, contains several of the island's major religious buildings, including the Cathedral, as well as a multitude of ancestral homes from the 17th and 18th centuries.

Cáceres
More than ten towers dominate the historic quarter of Caceres, delimited by Arab walls. Cobbled streets marked by medieval, fortified homes and Renaissance palaces make up the most beautiful sceneries in this city, which was declared World Heritage.
The local history is closely related to one the historic, peninsular routes: "Vía de la Plata" (the Silver Route), a Roman road that linked Seville and Astorga, used by the pilgrims who were headed to Santiago de Compostela. Pork products and shepherd recipes are the fundamental elements of the rich culinary tradition of this region, the dishes should be served with some of the excellent wines from Caceres.

Cuenca
This city in the province of La Mancha, which is a World Heritage Site, lies between the gorges of the Júcar and Huécar rivers. Its monumental historic quarter lies beside rocky walls in the heart of the Cuenca mountains. The Cathedral, Casas Colgadas (Hanging Houses) and cobbled streets charm the most hardened traveller. A former Franciscan convent houses the Cuenca Parador de Turismo, where guests can rest and enjoy the region's most traditional recipes. One of the best times for visiting the city is during the Religious Music Week, a festival of International Tourist Interest. Art, history, adventure sports, spas and hunting are some of the opportunities offered by this province in Castilla-La Mancha.

Alcalá de Henares
This town near Madrid, birthplace of the illustrious Miguel de Cervantes, author of “Don Quixote”, and home to one of the most prestigious universities in Spain, has been declared a World Heritage Site by UNESCO. Its rich monumental heritage, formed by churches, convents and university buildings, gives us a glimpse of life in Castilia during the Spanish Golden Age. Its historic quarter also has the “Mesón del Estudiante” Inn, which is part of the network of Paradores de Turismo. Walls with four hundred years of history make the perfect place to sample the best of the local gastronomy.
