Jigme Singye Wangchuck
One of Shakya Rinchen Rinpoche's main disciples built the original lower temple (Sonam Ghatsel temple) but it was destroyed by fire. It was rebuilt in the 1960s, during the Fourth King's (Jigme Singye Wangchuck) reign, with the support of the Queen Great Grandmother Ashi Kesang Choden Wangchuk.
