Guanajuato is a city in central Mexico. It’s known for its silver mining history and colonial architecture. Its network of narrow streets, alleyways and tunnels is typified by the Callejón del Beso (Alley of the Kiss), so named because the balconies are close enough for a couple to reach across and kiss. In a former granary, the Alhóndiga de Granaditas is an art and local history museum with pre-Columbian exhibits.
