León is one of Nicaragua’s most popular destinations, thanks to its gorgeous architecture. Most of it isn’t original—León was leveled by an earthquake less than a century after its founding in 1524—but the rebuild is lovely (and old!) in its own right. Particularly noteworthy is the Catedral de la Asunción, a neoclassical beauty that was finished in the early 1800s. The city was also home to Rubén Darío, perhaps Nicaragua’s best-known man of letters; today, the poet's house is open to the public as a museum.
