This is a leaf-shaped akroterion which had been part of a public building. It is a large-scale architectural element for decorative purposes which was placed on the ends of the crown of a public building.
It was found during the excavations at number 12, Carrer de Sant Cristòfor in the area of the cardo maximus, which is oriented north to south. It was part of the cover of the main sewer system on this Roman street at some point in the 4th century AD, when the sewer was repaired using architectural elements repurposed from public buildings, a common practice during that period.
