Roman market-place - macellum in Split

Some twenty years ago, foundations of a part of a large antique building consisting of orthogonal walls and three concentric circular walls were discovered at the site of Ad basilicas pictas, 500 meters north of Diocletian's Palace. The researchers interpreted the finds as remnants of an ancient odeon, which they dated to the first or second century based on the archaeological material. The new 2013/2014 excavations, conducted east of this site, in the area of Domovinskog rata Street, identified that the circular walls continued further to the east, forming a full circle and were located in a building with a square ground plan, its external dimensions measuring 67 x 67 meters. This paper will provide an overview of all researches to date and attempt to reconstruct the ground plan of the discovered building, its original purpose and the time of its construction.
