The rebuilt walls put up around the acropolis of Athens. A massive rebuild of these walls happened right after Darius the Great (father of Xerxes) destroyed the original temples of the acropolis. The temples made up the new walls. The Athenians built the wall with the old temples to remind themselves of their shame.
