Tula is a town of 28,432 (2005 census) in the southwestern part of the state of Hidalgo in central Mexico, some 100 km to the north-northwest of Mexico City. The modern town is known as Tula de Allende; also a state municipality that covers part of the southeastern portion of the Pre-Columbian city. The present-day municipality has a population of 93,296 and an areal extent of 305.8 km² (118.07 sq mi), which includes numerous smaller outlying towns, the largest of which are El Llano, San Marcos, and San Miguel Vindho.
Nearby are the remains of the ancient capital city of the Toltecs, also known as "Tula" or as "Tollan". Usually identified as the Toltec capital around 980 CE, the city was destroyed at some time between 1168 or 1179.
The site is at and around the junction of two rivers, the Río Rosas and the Río Tula. The two largest clusters of grand ceremonial architecture are nicknamed "Tula Grande" (the most visited by tourists) and "Tula Chico". Remains of other buildings extend for some distance in all directions. In the residential areas streets were laid out in a grid pattern.
