Bangkok, Thailand · Anantara · High Luxury
On the grand staircase of Anantara Siam, a 100-square-metre silk mural shows the founding of Bangkok and the Chakri dynasty, hand-woven and painted by the master muralist Ajarn Paiboon Suwannakudt, who died six months into the work; his daughter Phaptawan finished it with 27 apprentices over a year. The hotel was built in 1978 as the Bangkok Peninsula, then flew Regent and Four Seasons flags before becoming Anantara Siam in 2015, and a major renovation was announced for 2025.

History
Originally the Four Seasons Bangkok (1983-2015), Anantara took over operations in 2015. Opposite Royal Bangkok Sports Club in Ratchadamri.
Built in 1978 as the Bangkok Peninsula — designed by George Wimberley of WATG and featuring a 100-square-metre hand-woven silk mural of the Chakri dynasty's founding, completed posthumously by the muralist's daughter — the property has operated under four flags (Peninsula, Regent, Four Seasons, Anantara) before landing a USD 50 million renovation beginning 2025.
The setting
Anantara Siam Bangkok Hotel anchors 155 Rajadamri Road in Pathum Wan, at the edge of Ratchaprasong — an intersection developed from rice paddies into Bangkok's premier luxury corridor under Crown Property Bureau stewardship in the 1950s. The nearby Erawan Shrine and nine sacred sites have earned the district its nickname the Intersection of Gods. CentralWorld is eight minutes on foot; Lumphini Park twelve. BTS Rajadamri station connects the hotel to the full Skytrain network, and Gaysorn Village luxury boutiques stand opposite — a convergence of spiritual tradition, high-end retail, and Bangkok's most historically significant commercial intersection. 8 km from Grand Palace. 11 km from Wat Arun Buddhist temple.
