The town's main plaza, officially called Plaza Borda after José de la Borda, is commonly referred to as the Zócalo. On the north side of this plaza is the Casa Borda (Borda House), the most important non-religious construction in the city. The front facing the Zócalo has two stories, but the back, facing the Plaza de Bernal, has five. This is due to the uneven ground on which the house was built. Much of the house is now dedicated to the Casa de Cultura (Cultural Center) where classes in languages, fine arts and sports such as judo are taught. The rest of the main plaza is surrounded by silver shops, restaurants and bars.
