The UNESCO World Heritage Site consists of fourteen monasteries that are located south and east of Mexico City, most in the state of Morelos, with three in the state of Puebla. The monasteries in Morelos are located in the municipalities of Atlatlahucan, Cuernavaca, Tetela del Volcán (including the one in Hueyapan), Yautepec, Ocuituco, Tepoztlán, Tlayacapan, Totolapan, Yecapixtla and Zacualpan de Amilpas. The three in Puebla are located in Calpan, Huejotzingo and Tochimilco. Most, but not all, of these monasteries are located on the periphery of the Popocatepetl volcano.
