2 Best Sights in Paris, France

For centuries, this 170-foot bell tower guided pilgrims to a starting point of the Chemin de St-Jacques (Way of Saint James). Built in 1508 in the Flamboyant Gothic style, it's all that remains of the Église St-Jacques-de-la-Boucherie, which was destroyed in the French Revolution. Purchased by the city in 1836, the tower languished until a three-year renovation, completed in 2009, restored 660 tons of stone and statues, including the gargoyles hanging from the upper reaches and the figure of Saint James gracing the top. Blaise Pascal was among the medieval scientists who conducted experiments here (his involved gravity), which is why his statue sits at the base. If you wish to enter the tower, guided tours are occasionally offered in spring, summer, and early fall by reservation only.

Paris's least regarded architectural eyesore had been scheduled to undergo a major overhaul, which has since been postponed indefinitely. Someday it will have a sparkling new facade with planted terraces and a renovated, ground-level shopping center, but in the meantime, a quick elevator ride still whisks visitors to the top of one of continental Europe's tallest skyscrapers, where you can take in panoramic vistas of Paris from the glass-enclosed observation deck on the 56th floor. On a clear day, you can see for 40 km (25 miles). Built in 1973, the 680-foot building also sports a rooftop restaurant that offers some of the best views of Paris and beyond. The open-air rooftop is accessible for those who can walk up three extra flights to floor 59 (where there's no elevator access).
