One of my favorite things I did as a tourist in Prague was to cross back from the Castle hill over the Charles bridge. In spite of the crowds (or because of them), this felt like a festive pilgrimage of sorts. It is entirely a pedestrian walkway now. The bridge’s balustrades suppport 30 very large Baroque statues of saints and prominent rulers (many of whom were also canonized), and along the sides are numerous arts and crafts vendors. The bridge is the oldest in Prague, begun in the mid-14th century, and added to throughout the next 400 years.
