Wat Benchamabophit, called the Marble Wat because of the white Carrara marble of which it's constructed, is an early-20C temple designed by Prince Narai, the half brother of Rama V. It's the most modern and one of the most beautiful of Bangkok's royal wats. Unlike the older complexes, there's no truly monumental wihaan or chedi dominating the grounds. Many smaller buildings reflect a melding of European materials and designs with traditional Thai religious architecture. Even the courtyards are paved with polished white marble.
