This tour was a fascinating look at a bit of history completely new to me. Cisterns and tunnels under Naples dating to the Roman empire that I had never heard of before. Stories and artifacts from their use as air raid shelters during WWII were particularly interesting. Ansara was a well informed and engaging guide. Note that there are a LOT of stairs to go down, and the tunnel floor is not flat and smooth. My spry 84 year old father did it, and was exhausted afterwards. People with walking issues should consult the guides before attempting this tour.
