In the aftermath of the Gorkha earthquake of 25 April 2015, archaeological and architectural work has been conducted at the holy site of Svayambhū (Monument Zone of Kathmandu Valley World Heritage Site). Being the focal point of a large number of devotees, a prompt and adequate emergency response was needed to secure and protect the cultural and architectural heritage of the temples, houses, shrines and artifacts. Two methods were practised: a post-disaster archaeological investigation and an architectural inventory and survey. The former resulted in an archaeological analysis of a stūpa, and the latter was conducted to produce an up-to-date map of all buildings in their current state and an inventory of each structure with relevant diagnosis, photographs and situation outlines.
