When I visited Rome in 1999, I arrived on Good Friday. My Dad and I decided to head to the Coliseum to see the Stations of the Cross. It was incredible. First walking through the Circus Maximus and approaching the Arch of Constantine is awesome, when you realize all the history. Then you crest the hill and there it is. Quite beautiful, quite intense.
Indescribable, isn't it! I have visited the Colosseum several times. It is a place where time is frozen and one can practically hear the cheer of the crowds and the singing of the Christians as they are led forth to their execution.
