Wat Mongkhon Bophit is an "active" temple compound, and throughout the day many people visit and worship the Buddha image.
Interestingly it lies adjacent to Wat Phra Si Sanphet, and therefore both the ruins of Wat Phra Si Sanphet and the more contemporary Wat Mongkhon Bophit can be visited the same morning or afternoon.
The main feature at Wat Mongkhon Bophit is the large bronze (gilded) Buddha image, named Phra Mongkhon Bophit, which is close to 17 meters high (when including the 4,5 meters high base).
