Many of these homes and manor houses of the former haciendas still remain in and round Tlalpan center. As the urban sprawl of Mexico City only began to reach this area starting in the mid-twentieth century, much of the former village has retained its provincial streets, older homes and other buildings with façades of reds, whites, blues and other colors, although a number have been converted into other uses such as cafes, restaurants and museums. This makes the area similar to neighboring Coyoacán, and like this neighbor, Tlalpan center is popular with visitors, especially on weekends as people come to see its provincial main square/garden, mansions, narrow winding cobblestone streets lined with large trees, eat in its restaurants and cafes and visit its many nearby parks and other green areas. One popular area with cafes and restaurants is La Portada, on one side of the main plaza. Tlalpan center has eighty structures from the 16th to the 20th centuries that have been classified by INAH as having historic value. Some of these include old Tlalpan Hacienda, the former home of the Marquis de Vivanco and the San Agustin parish church. The borough of Tlalpan has sought World Heritage Site status for the area because of these structures, the area's history and the nearby site of Cuicuilco. The center of this former village is the main square or garden officially called the “Plaza de la Constitución” but better known as the “Jardín Principal” (Main Garden). Visually, what stands out is the large kiosk in the center, but historically more important is the “Arbol de los colgaldos” (Tree of the Hanged). This tree, still alive, was used to hang political enemies and bandits, including those opposed to the invading French Army during the French Intervention in Mexico. On weekends, vendors set up stalls selling handcrafts and other items. To one side of the plaza, there is a cantina called La Jalisciense, one of the oldest in Mexico City, having been in operation for over 135 years. Facing the Jardín Principal, there is the “Palacio de Gobierno” (Government Palace), which was the site of the government of the State of Mexico, when Tlalpan served as state capital for six years in the early 19th century. Since then, it was used as a barracks for Benito Juárez’s soldiers, a jail, a residence for the Empress Carlota and the site of the Instituto Literario (today the Universidad Autónoma del Estado de México) .
