The Wall of Santa Eulalia constitutes an essential reference in the tourist and cultural offer of the city of Murcia .

In the city centre there is a part of the medieval walls of Murcia where it is possible to appreciate the evolution that the urban defences experienced throughout the centuries.

The history of Murcia can be summed up in the transformations and adaptations of the wall to the needs of the city: it was founded in the 9 th century, developed during the 12 th century, it was conquered by the Castilians in the middle of the 13 th century, used as a border during the 14 th and 15 th centuries and, finally, it disappeared for defensive reasons once the kingdoms of Castile and Aragon were united and when the nazari sultanate of Granada was conquered in the end of the 15 th century; it became decadent and disused in posterior centuries but it was restored as a urban element in the end of the 20 th century.

The historical importance of the Wall of Santa Eulalia, as well as the peculiarity of the architectonic intervention, show how the archaeological remains which can be found in situ have been respected and it is still possible to relate them with the spaces they were located in.

The Centre has been built over an opened excavation in Santa Eulalia Square , next to the chapel of San José . In that excavation, which is about 110m2, the remains of an Arab wall from the 12 th century are kept. In the 15th century another wall was built on the Arab one coinciding with the access tower. This project constitutes the first phase of intervention in the archaeological environment, that in a near future will be expanded, creating new projects in close archaeological sites, which are about 50m2 in total, and an Arab necropolis located in the same square, 25 metres away from the Centre. All these archaeological sites were originally connected and that is why the project has been thought as a global intervention with different phases in the area, connecting all the sites through subterranean galleries.
