 Volcano danger to these and the over 100 other historical monuments in the area is low because lava flows from the volcano are generally slow and monuments were not built in the low-lying areas that lava tends to run to.To further publicize the World Heritage monasteries in Morelos, the state promotes the eleven as the Route of the monasteries or the Route of the Volcano.The route begins in Cuernavaca with the monastery church serving as the city's cathedral.
