This pavilion was built in tribute to His Royal Highness Crown Prince Maha Vajiralongkorn and Her Royal Highness Princess Maha Chakri Sirindhorn. It is normally used for morning and evening prayers of the Ubasok (devout laymen) and Ubasika (devout laywomen), and serves as novice’s living quarters during their summer ordination at Wat Yanasangvararam. In the geo-astrological view, this pavilion represents one wing of a swan while its pair, the SorWor KorWor Pavilion, represents the other wing.
