My girlfriends and I were traveling through Eastern Europe during our Peace Corps stint and heard that one of the 7 Chakras was in Wawel Castle in Krakow, Poland. We were also told that guides in the castle wouldn't tell us where it would be so we just had to "feel" it out. We spent over a hour, trying to "feel" the energy and touching parts of the walls but could never find it. On one of the best trips I have ever been on, it was one of the most entertaining adventures. The Wawel Castle has fascinating architecture and great stories so we really felt like the whole experience was awesome.
