In building Sanctuary B at the end of the sixth century B.C., the Tartessians placed an altar in the shape of a stretched-out oxhide directly over the earlier circle-and-triangle altar of Sanctuary C. Archaeologists have recovered coal and ash from the altar area, suggesting that worshipers in Sanctuary B made burnt offerings to the gods.

Visitors to Sanctuary B entered the complex through two towers in the building’s eastern wall—where the builders of the final sanctuary, Sanctuary A, also placed their entranceway’s huge trapezoid-shaped towers.
