This glass building built in modified Indian-Thai style is the ordination and principal recitation hall of the Monastery, as well as a symbolic site of the Buddha’s cremation. The building features footprints of the Buddha, a reclining Buddha, and a principal Buddha offered by Princess Ubol Ratana, the eldest child of King Rama IX. The glass structure makes this ubosot and cremation site distinct from other ones in Thailand. The lucid material represents the importance of maintaining transparency and purity when doing good for others. The top of the ubosot contains dirt from all provinces in Thailand–and Kushinagar, where the Buddha took his last breath.
