I’m not Catholic. Not even much of a practicing Christian, but I must confess I felt a little chill the other night walking past Köln’s Cathedral. Not from the cold of the night, nor from fear. My engaging German hosts had just informed me the Cathedral was built with sufficient grandeur to house the relics of the Three Magi spirited away from Milan in 1164. For hundreds of years pilgrims from around the world have converged on the Cathedral, adding to the 20,000 visitors a day. The site is sacred and steeped in history. For a few years it was even the tallest building in the world until eclipsed by the Washington Monument in 1884. I couldn’t escape the Cathedral’s history as we walked past it on this cool, clear October night.
