Founded in 1845, this is Cuba's largest and perhaps most renowned cigar factory, producing around 5 million cigars a year. The off-yellow-and-rust trimmed, neoclassical facade is resplendent in the Havana morning sunlight. (You can take your best photos of it from the west-side windows of El Capitolio.) Throughout the day, you can stop in and buy cigars from the well-stocked shop, La Casa del Habano.
