The Loha Prasat (โลหะปราสาท) is part of
Wat Ratchanaddaram (วัดราชนัดดาราม).
It is a multi-tiered structure 36 m high and having 37 metal spires,
signifying the 37 virtues toward enlightenment.
It is the third Loha Prasada (brazen palace) in existence,
modelled after the earlier ones in India and Anuradhapura, Sri Lanka.
