Heads turn twice when passing hebrew letters arching under the statue of Jesus on the famed Charles Bridge. Years ago, and a boosting a large Jewish community, one jewish man forgot to remove his hat when passing. He was fined and the government used the fine to post the hebrew over jesus stating "Holy, holy, holy" as humiliation. Over the years, society's successful attempts to remove the letters worked and they were torn down. Prague now has a preservation law in which nothing historic is allowed to be touched and so imitable letters were re-hung and still line the bridge today.
