An Example of Fit-for Purpose Use of Materials in Roman Architecture: P Temple, Side, Antalya/Turkey

. The high-podium Roman Period temple, with a semi-circular plan scheme, was discovered by Lanckoroński and his team in Side, Turkey and named after ‘P’ in 1890 [1]. The temple was unearthed by Mansel [2] and his team in 1947 through archaeological excavations. In 2013, further studies started on the temple. The aim of the still ongoing work is to seek answers to such issues that haven’t been clarified yet, as the plan scheme, to whom it was dedicated, and the date of construction. In this context, the construction structure of the Temple P was investigated during the present study based on in-situ and precise documentation: At least five different types of stones were classified by purpose, including conglomerate, travertine, sandstone, marble and rubble stone mixed with mortar as infilling material. It was seen that fit-to purpose use of the material was considered more important than the ideal and repeated dimensions of the building blocks. Moreover, local material was used except for the outsourced marble. In addition to the large-sized clamps and dowels in the load-bearing core blocks of the walls, the spaces between the coatings and the load-bearing core were filled with mortar. In this construction technique, opus revinctum and opus caementitium were used together. The partition walls separating the three rooms of the lower floor and the vault cover made with mortar and formwork system belong to the construction period of the temple. However, there are indications that the outer walls, about 2,5 m thick, originated from the foundations of a precursor structure. Four construction stages of the pillar profiles of the orthostat
