Tlalpan is the largest area of the 16 administrative districts ( delegaciones ) of Mexico City. In 2010 there were about 650,000 inhabitants here. The place name comes from the Nahuatl and means " above the earth " ( Tlalli = earth, pan = on ). Tlalpan is located in the southwest of the urban area and is bordered to the north by Coyoacan, on the west by the district Magdalena Contreras, on the southwest by the State of Mexico, to the south by Morelos, on the east by the districts of Xochimilco and Milpa Alta.
In the area of today's Delegación Tlalpan are the oldest human settlements in the valley of Mexico Cuicuilco, Ajusco y Topilejo. Cuicuilco was 650-100 BC settled and had about 20,000 inhabitants.
Tlalpan was at the time of the Aztecs is an independent site south of Lake Texcoco located in the city of Tenochtitlan. Hence the name, as Tlalpan in contrast to the nearby areas in the lake is not on " floating islands ", but on solid ground.
The Delegación has a total area of more than 4,700 acres, most of which ( about 80 %) are forest, fallow land and agricultural areas; less than 20% are residential and industrial areas. In the area of Tlapan is among other things the extinct volcano Xitle whose eruption around 100 BC destroyed the cultural center of Cuicuilco.
From Cuicuilco the remains of a pyramid are obtained, which was originally about 80 meters long and 20 meters high.
Located in the historic center of many colonial houses still remain. On building of the district administration are large-scale murals that show the history of the place. Close to the center of Tlalpan with an almost rural looking Zócalo is a large park, the " Bosque de Tlalpan ", a popular excursion destination of the inhabitants of the capital. On the road to Ajusco is the amusement park "Six Flags Mexico ."
