Piedra大楼矗立在Paseo de Jesús大街的一侧，完全由来自Porcuna采石场的石料打造而成，宛如一座纯手工砌筑的纪念碑。大楼的建造者是一位来自当地的采石场工人，名叫Antonio Aguilera Rueda。他花费了29年的时间来完成这项作品。这座建筑不属于任何项目，它仅仅是一位采石场工人的逻辑与知识的产物。
Casa de la Piedra, a handcrafted monument entirely made of stone from stone quarries in Porcuna (Jaén), rises on a side of Paseo de Jesús. The author of this work was the local quarry worker Antonio Aguilera Rueda. He devoted 29 years of his life to accomplish his creation. The house was made without any project, just with the logical knowledge developed by a person who worked in the field of stone quarrying.
The construction was carried out by means of colossal stone structures, more than 3,000 kg each one, laid in a primitive way without using any binder, working entirely by compression. This lack of applied technique will provoke, fifty year later, a fast deterioration in the monument. Sinking of some pillars, loss of structural stability in the north tower or appearance of significant chemical pathologies will be the reasons that force the city council, current building manager, to intervene urgently.

The intervention will have a surgical purpose, dealing with each pathology accurately. To do this, it will be necessary to remove a large number of additional elements, which had been added over the years by the family that lived there. After a major cleaning and restoration work in the stone, a sophisticated lighting system will be installed in order to highlight all the beauty in the stone craftsmanship. At the same time, a large set of ramps, made of marble concrete, will give access to a crystal lift, which will be the only discordant element but also the one that will enable a total accessibility to the building. This was a main requirement from the city council. In conclusion, a project that will aim, at all times, to show the stone without touching the stone.
