Boudhanath Stupa is the largest stupa in the Kathmandu Valley at about 131 feet (40m) tall, and one of the largest and most important Buddhist stupas in the world. The all-seeing red, white and blue eyes of Buddha are painted on all four sides of the stupa, similar to Swayambhunath, and surrounded by hundreds of fluttering prayer flags, prayer wheels and small images of Buddha. It is central to the Tibetan culture in Nepal and is said to date back 500 years. Buddhist festivals are a hive of activity when thousands of Buddhists join together to join in the sacred rituals, such as the Tibetan New Year, or Lhosar, in February every year.
