Originally, Pura Batur and the village of Batur were located down in the caldera at the foot of Mount Batur, an active volcano. A violent eruption in 1926 destroyed both the village and the temple, except for the most important shrine, an 11-tiered meru dedicated to Dewi Danu. The villagers moved to the highest and oldest rim of the caldera, where they rebuilt their village and the temple.[source]
