Wat Ratchanatdaram Worawihan
Nestled in the grounds of Wat Ratchanatdaram Worawihan, Loha Prasat is known as the “metal castle”. It was built in 1846, and is 36 meters featuring 37 spires made of metal, each symbolizing the 37 virtues leading to enlightenment. At its highest level is a relic of the Buddha.
Loha Prasat is the only multi-floored and square-based temple construction that is in existence today. For a small entry fee, you can explore this rare piece of architecture. Due to its uniqueness, Loha Prasat was submitted to UNESCO to be considered as a World Heritage Site. While the temple has yet to be bestowed with that title, it has its own noteworthy place in the Bangkok cityscape.
