The shrine inside the cella of the temple A of Agrigento, generically assigned to the Roman age, is a structure largely ignored by the modern scientific literature. It belongs with the deep transformations which, since the First Punic War, have concerned some of the great temples of Agrigento, from the so-called Olympieion to the temple A. The article illustrates a history of the investigations on the shrine, outlining the main issues which emerged, such as its dating or the typological problem, settled by the division into three parts of the end of the naos. Other important questions are to be added, such as the reconstruction of the worship practices connected with the small building, their relationship with the surviving structures of temple A. As a contribute to the interpretation of the whole area around the so-called lower agorà on the eve of the Roman siege of the city, the article identifies a reuse of the temple A within the fortification built in a state of emergency in 255-254 b.C. in order to defend the natural passage at the South-West part of the city, and links it to the similar and already known use of the Olympieion. This occasion probably constitutes a terminus post quem for the construction of the shrine and the reorganisation of the worship, while it is possible to identify a terminus ante quem in the statue of Asclepius of Augustan age, found in one of the two rooms flanking the naiskos.

The common practice of the restoration work is to join the marble fragments together with threaded titanium bars, inserted into drilled holes inside the marble and fixed into place with cement mortar. The estimation of the design loads of structures such as the Acropolis monuments is a very difficult task especially when the seismic response is concerned. For this reason elaborate and accurate methods and analytical tools have been used with very good results. At the recent times discrete elements analysis seems to predict accurately enough the response of these structures and provides a time effective method as opposed to the use of finite element analysis. But the use of such methods for calculating the required reinforcement in each fracture is not yet feasible in a large scale, thus simplified methods are still used to facilitate the work on the site. The methodology of calculating the required reinforcement so far consisted of simplified two dimensional analogies of the fractures and the reinforcement as well as the loading conditions. This article presents a concise and simplified methodology for the calculation of the required reinforcement for fragmented architectural members taking into account the effects of the three spatial dimensions (geometry of the fracture, geometry of the reinforcement and geometry of the loading). In this approach the problem of calculating the expected tension of the reinforcement in complicated spatial forms of fracture is dealt with. The important features and requirements meant to be kept by this project was that the final product should maintain the character of an easy to use and accessible tool that would respond in real time to facilitate the work of the civil engineers on the site.
