The Temple of Athena Chalkioikos
The Temple of Athena Chalkioikos, sitting atop of the Acropolis, was discovered in 1907 by archaeologists of the British School of Athens. The interior walls were originally decorated with bronze or copper sheets, which is where the name of the temple is derived. It is believed that in the temple there once stood a series of statues depicting Athena's birth. These statues are mentioned in several ancient writings.
The area around the temple was also used as grounds for an annual celebration in which Spartans would make sacrifices. Public rallies and horse races were also held at the temple.
The temple remained in use up until around the 4th century. Considering it's important location in the city, the temple is thought to have been a significant place of worship to the goddess Athena Chalkioikos.
