Monte Albán - Stela 18

On the north side of the Sistema IV is the badly weathered Stela 18 thought to date from the Monte Albán II phase. It is the only stela still in existence from that time and may have been erected at about the same time as the original construction of System IV, which was built from heavy stone blocks in the cyclopean style of this epoch. Between the building and the north platform lies a flat site with chambers and several tombs.
