The Greeks have a Tomb of the Unknown Soldier. It is located outside of the Greek Parliament and is guarded by the Evzones, a ceremonial assignment within of the Greek Army.
We just were not a good match for either Athens or Istanbul. I really looked forward to visiting both. Our several prior trips to Europe were on trans Atlantic one-way cruises. We arrived in Europe refreshed, ready to go and with no jet lag. For this trip we flew to Athens prior to boarding a cruise ship and much of our time there was spent acclimating to the right time zone. Also, we are not much on going to museums and ancient ruins, which of course is what Athens is all about. It seemed as if the entire city was tagged with spray paint. Very, very few attractive painted murals, mostly sloppy tags.
