All of Paris is well trod. If a single footprint could be allotted one-quarter inch in height, then all the individual footprints trod at Tour Eiffel or Notre Dame for just one year, if stacked, would create a pinnacle nearly forty miles high. And yet, given the intricacy of the city, no two wanderings ever are likely to be the same. Paris delivers the grand sense of place that is dreamily anticipated, and yet also manages to yield a surprisingly personal experience. A seven-story height limit on buildings and plenty of wide-open spaces make the famous attractions visible from afar, sticking out like cartoon drawings.
