The largest stones including the lintels and gate jambs weighed well over 20 tonnes; some may have been close to 100 tonnes. Somewhat later, toward the end of LHIIIB around 1200 BC, another, final extension to the citadel was undertaken. The wall was extended again on the northeast, with a sally port and also a secret passage through and under the wall, of corbeled construction, leading downward by some 99 steps to a cistern carved out of rock 15 m below the surface. It was fed by a tunnel from a spring on more distant higher ground. Already in LHIIIA:1, Egypt knew *Mukana by name as a capital city on the level of Thebes and Knossos. During LHIIIB, Mycenae's political, military and economic influence likely extended as far as Crete, Pylos in the western Peloponnese, and to Athens and Thebes. Decline Mycenae was among the numerous Aegean sites destroyed as part of the Bronze Age Collapse around 1200 BC. The causes of these destructions are unknown, but proposed explanations include enemy attack, internal strife, and natural disasters such as earthquakes. Unlike many other sites, Mycenae was partly rebuilt after this destruction, though it was no longer the center of a centralized literate bureacuracy. Pottery finds suggest that Postpalatial Mycenae eventually regained some its wealth, before burning once again. After this period, the site remained sparsely populated until the Hellenistic era. Archaic and classical periods A temple dedicated to Hera was built on the summit of the Mycenaean citadel during the Archaic Period. A Mycenaean contingent fought at Thermopylae and Plataea during the Persian Wars. In 468 BC, however, troops from Argos captured Mycenae, expelled the inhabitants and razed the fortifications. Revival and abandonment Mycenae was briefly reoccupied in the Hellenistic period, when it could boast a theatre (located over the Tomb of Clytemnestra). The site was subsequently abandoned, and by the Roman period in Greece its ruins had become a tourist attraction. The Ministry of Culture, Education, and Religious Affairs is currently in charge of the site. In
