Thailand Celebrates King Bhumibol Adulyadej’s 85th Birthday

To see more of the festivites in Thailand, visit photos posted from the Royal Plaza (ลานพระบรมรูปทรงม้า) in Bangkok.

Bhumibol Adulyadej, Thailand’s king and the world’s longest-serving head of state, turns 85 years old today. King Bhumibol, also known as Rama IX, has ruled Thailand for more than 66 years, and is a popular figure throughout the country.

Many Thais, clad in yellow—a color symbolizing devotion to the monarch—have camped for days at the Royal Plaza in anticipation of the day’s festivities, which include fireworks, thousands of vividly colored marigolds, and a performance by Korean pop singer Psy.
