The indigenous Nepal Bhasa term for Kathmandu is ''Yen''. The Nepali name ''Kathmandu'' comes from Kasthamandap, which stood in the Durbar Square. In Sanskrit,  () means "wood" and  () means "pavilion". This public pavilion, also known as ''Maru Satta'' in Newari, was rebuilt in 1596 by Biseth in the period of King Laxmi Narsingh Malla. The three-storey structure was made entirely of wood and used no iron nails nor supports. According to legends, all the timber used to build the pagoda was obtained from a single tree. The structure collapsed during a major earthquake in April 2015.
