No wonder the lines to get inside St. Peter’s Basilica are some of the longest in Europe: It’s home to world-famous architecture (many consider the dome atop St. Peter’s Basilica to be Michelangelo’s greatest achievement), one of the best views of Rome, and, oh yeah, the pope. The best way to visit this legendary site is to stroll in just after its 7 a.m. opening, make your way up to the dome, and look outside: You’ll get the spectacular view practically to yourself. You can take a free English-language tour if you visit between October and May. And keep in mind, there’s a strict dress code.
