Findings at this archaeological site were unearthed by the pioneer excavations of the British School of Archaeology starting in 1910. Excavations resumed in the early 1990s, primarily in the areas of the ancient theatre and the merchant stalls.
The most significant monuments of this archaeological site include:
The Temple of Athena Chalkioikos whose position has been defined by few surviving relics found at the northwest end of the Acropolis. The temple, designed by the architect Vathyklis from Magnesia, had an interior design adorned with copper sheets (dated 6th century BC onwards) to which it owes its name (chalkioikos = copper). From the inscription by Damononos (dated before 430 BC), it seems it was called Temple of Athena Poliouchos (Guardian of the City). Pausanias adds that the temple was left unfinished until Gitiada, a local craftsman, built both the statue of the goddess and completed the temple. The temple also served as a place of refuge for Lycurgus, Pausanias and Agis IV.
The ancient theater of Sparta on the south side of the Acropolis is a product of the early Imperial Period. The orchestra, the retaining wall with engraved inscriptions of the rulers of Sparta in Roman times and the concave portion of the large theatre has been preserved. The concave of the theatre was dug into the southwest end of the Acropolis. The retaining wall of the concave is marble and its east side was engraved in the 2nd century AD with various inscriptions. The theatre was used primarily for public gatherings and celebrations. It had no permanent stage. For theatre performances, a wooden, mobile stage equipped with wheels was easily moved into position. Nearly all the findings of the ancient theatre that were discovered by the British School of Archaeology date back to the Roman Era. https://www.exploresparta.gr/tourism/en/the-acropolis-of-sparta/
