Historic sites

Modern Mérida has expanded far beyond its original city walls, but many old Spanish colonial buildings and several old city gates can still be seen in the centro histórico, which is among the largest in the Americas. Many large and elaborate homes from the early 20th century still line the main avenue called Paseo de Montejo. For example, "Las Casas Gemelas" (The Twin Houses) are two side-by-side French and Spanish style mansions completed in 1911 by Camilo and Ernesto Cámara Zavala. Owned by the Barbachano and Molina Méndez families, they are two of only a few houses that are still used as residences on Paseo Montejo from that era. During the Porfiriato, the Barbachano house held cultural events that hosted artists, poets, and writers. In the mid-1900s, the Barbachanos hosted aristocrats including Princess Grace and Prince Ranier, as well as first lady of the U.S., Jacqueline Kennedy.

The historical center of Mérida is currently undergoing a renaissance, as people and businesses move into these old buildings and restore them. Many of these restored buildings now serve as office buildings for banks and insurance companies. Other important historic sites in the city include:
