We visited Mycenae, which has archaelogical ruins from the 16th Century BC. We had seen artifacts taken from this site at the museum in Athens- gold and bronze jewelry, vases, bottles, weapons, etc.
We also visited Epidaurus, which has one of the most intact amphitheatres in Greece and could seat about 7,000 people. It had great acoustics, and it was huge. That was cool to see, since I've been involved with theatre for so long. Tomorrow we fly to Santorini, which should be fun.
