Wat Ratchanatdaram
วัดราชนัดดาราม
The Iron Castle — a black 37m spire with 37 metal prangs.
Address
2 Maha Chai Rd, Khwaeng Wat Bowon Niwet, Khet Phra Nakhon
About
One of only three such Loha Prasat structures ever built (the other survivors are in Sri Lanka and India). A dark, quiet staircase leads to a spire-studded rooftop terrace — dramatically different from Bangkok's usual gold.
Best time to visit
Late afternoon — the spires glow bronze at golden hour
Tips
Free climb. Sometimes closed for ceremonies; check before you go.
