Wat Saket is easily recognized by its golden chedi atop a fortress-like hill near busy Ratchadamnoen Road and Banglampoo. King Rama I restored the wat, and 30,000 bodies were brought here during a plague in the reign of Rama II. The hill, which is almost 80m (262 ft.) high, is an artificial construction begun during the reign of Rama III. Rama IV brought in 1,000 teak logs to shore it up because it was sinking into the swampy ground. Rama V built the golden chedi to house a relic of Buddha, given to him by the British. The concrete walls were added during World War II to keep the structure from collapsing.
