This monument commemorates the support of its benefactor-founder of a theatrical performance at the nearby theatre of Dionysus, the earliest theatre in the world - that’s the answer in case you wonder just what that strange structure on Tripodon Street is. It was built in 335BC by Lysicrates and is also known as the “Lantern of Diogenes” in reference to its unusual shape. The circular building rests on a square shaped limestone podium and includes a portico of six Corinthian columns. It also has a frieze featuring the life of Dionysos, the god of wine and revelry. In 1669, the structure was handed over to Capucin monks, who used it as a study room. The Lysicrates monument is the best preserved of its kind, mainly due to the efforts of French archaeologists Fr. Boulanget and E. Loviot who restored the area in 1887.
