This article presents a new built chamber tomb from Argos. The tomb was found intact, allowing for detailed observations on its architecture and construction. It contained the remains of at least fifteen burials, together with abundant Mycenaean pottery, bronzes, ivory items, a sealstone and other small finds, dating from LH I to LH III B1 (although most are LH I–II B/III A1). Another two tombs of the same type have been found on the site, dating to LH I and LH II A. Comparison with other Early Mycenaean graves from Argos suggests that built chamber tombs were the largest and wealthiest, apparently belonging to local élite groups.
