Consolidation of the Matrera Castle Keep Tower

This medieval tower has always been a historical landmark due to its strategic position in the latest “Nazari” border. However, it had partially collapsed in 2013, losing part of its imposing volume and putting at risk not only the architectural stability of the rest of the tower, but also its role as a landscape landmark. Therefore, our project was to consolidate such a landscape icon.

With compatibility and authenticity criteria, the intervention looks at structurally consolidating the elements that were at risk, to differentiate the additions from the original structure, avoiding mimetic reconstructions (that our law prohibits), and recovering the volume and tonality that the tower originally had as a landscape icon.

Previous historical, constructive, functional, structural and pathological analyses, as well as the archaeological supervision that has taken place have been important to define the details of the project. New discoveries have appeared during the works that have served to recover part of the interesting history of this monument of cultural interest.​

The very limestone that had collapsed was re-used for the buttresses that guarantee its stability and for the reinforcements/protections of the internal degraded cores that had lost their exterior stonework. The top was executed in order to consolidate the slender wall that remained after the collapse and that was running a serious risk of overturning. In its exterior face, the flesh was removed and the original white covering was retained in its interior face as well as an interesting fresco painting of a boat in ochre tonality. All the edges were also rethought from the details of geometric existing geometrical elements, in order to mark its original volume.

In parallel to the practical intervention of movable heritage, its historical value has also been enhanced, facing its original volume using a continuous coating (mortar of lime) similar to the one which originally covered it.

Consolidation and restoration in the area of “Sant Francesc” and “La Pardala” in Morella Castle (Spain)

The general criterion for intervention has been to restore and consolidate the existing masonry, maintaining their ruinous physiognomy, avoiding reinterpretation of the original state.

For the necessary added structural elements, compatible materials such as lime concrete, with stainless steel and glass fiber reinforcing have been used, with tones and textures that integrate with the rest of the historical stratigraphy of the existing and discovered masonry. In the same way, for necessary added functional elements such as carpentry, stainless steel with titanium steam treatment has been used, giving it a finish that integrates with the rest of the intervention.

In the interior of the walls, an important volume from Carlist War period fillings has been removed because it structurally affected the wall. Numerous archaeological remains appeared, and were deposited in the Museum of the Castle of Morella, as well as the finding of three lime ovens, leaving visible  medieval rammed-earth. For the collection of rainwater, the main cause of the pathologies caused in the masonry of the Castle, a system of diffuse pavements and pipes has been arranged that direct the waters to a pre-existing outdoor pool.

Recovery of “El Pilar” orchard 

Several springs emerge from the skirt of the “Cruz” Mount that, forming a territorial frame, irrigate a set of historical gardens on the Jerez´s field accross a system of hatches and a curious rule for the distribution of the water. The humble housing of the horticulturists of “El Pilar”, of the XIXth century, consists in two diaphanous plants and a sloping cover, with walls of stone and wooden floors. The intervention goes to consolidate structurally the existing building, to support the spatial clarity of his interesting diaphanous spaces and to recover the original levels of the building and his relation exterior – interior.

The foundation is reinforced, the walls are sewed, the original floors are recovered, a few pieces that give service to the housing are inserted in the spaces and, on his exterior court, the original levels have been recovered, creating an intimate space that gives continuity to the ground floor of the housing. This court separates from the adjacent road, on a top level, for a wall staggered of concrete that allows to create some gardens and leads the dug upped water, that communicates the diverse orchards, and it´s taken up to a pond, producing a constant and relaxing sound that refreshes and recovers the essence of the original space.
