The colonial center of Zacatecas is a UNESCO World Heritage site and features elaborately decorated buildings, cobblestone streets, and wrought-iron lanterns. The ironwork on each of the buildings in the town center is unique. Nearly all of the city center buildings are nineteenth century or older; the topography and irregular street pattern (most streets are too steep and narrow for vehicles; many have steps in them) almost make one think of a medieval European city. The city, built on the site where silver was discovered in the 1530s, is crammed into a narrow canyon, with houses and churches perched on its nearly vertical walls.
The Cerro de la Bufa, a mountain with a very distinctive shape, is in the center of the city and, along the cathedral, is one of the city's most recognizable landmarks. The best way to get to the top is using the teleferico (cable car) which takes you you from the Cerro del Grillo to the top of La Bufa. Once at the top of La Bufa, don't forget to visit the memorial to Pancho Villa and the observatory, one of the oldest in this part of Mexico.
Zacatecas has an international airport (ZCL). It's an easy taxi ride from the airport to the colonial center.
