This Buddhist temple is also called the Loha Prasat, which means metal castle or metal monastery. It's named after its metal towers that make it the only one of its kind in the world. The temple boasts 37 metal spires that represent the 37 Buddhist virtues.
The Wat was meant to be a copy of a similar Buddhist temple on Sri Lanka, which is now destroyed. Although its construction started in the 19th century, it was only finished recently.
Even though there is no official entry fee, you may be asked for a small donation before you proceed into the temple. Tourists are free to climb all the way to the top of the temple, where there is a small shrine. Here the devotees place their offerings.
The temple is still in use, so there are monks to be seen, living their day to day lives, contributing to the unique feeling of the place. Since the temple is a place of worship, there is a mandatory dress code - clothing that does not cover the knees or the shoulders is considered inappropriate.
Admission is free.
