Watthana or Vadhana (, ) is one of the 50 districts ("khet") of Bangkok, Thailand. Neighbouring districts are (from the north clockwise): Ratchathewi, Huai Khwang, Suan Luang, Phra Khanong, Khlong Toei, and Pathum Wan. History. Watthana became a separate district by splitting from Khlong Toei in 1998 to provide better service to its population. The district obtained its name from Princess Galyani Vadhana, the elder sister of King Bhumibol Adulyadej. Watthana or Vadhana means 'development'. The area is among the most developed parts of Bangkok. On 1 January 2009, Watthana was the location of the Santika Club fire, which killed  66 and injured 222. Administration. The district is divided into three sub-districts ("khwaeng"), from west to east: They are all named by adding Nuea, meaning North, to the corresponding subdistricts in Khlong Toei district. Places. Encompassing the area between Sukhumvit Road and Khlong Saen Saep, Watthana is one of the commercial districts in Bangkok, with many condominiums and hotels.

Besides the eastbound Sukhumvit, prominent roads in the district include several odd-numbered sois (branch roads) from Sukhumvit: Nana Nuea (Sukhumvit 3), Asok Montri (Sukhumvit 21), Phrom Phong (Sukhumvit 39), Thong Lo  (Sukhumvit 55), Ekkamai (Sukhumvit 63), Sukhumvit 71 (Pridi Banomyong) and a small portion of On Nut (Sukhumvit 77). Symbols. The emblem of the district shows a pavilion, which refers to the residence of Princess Galyani Vadhana, the name patron of the district.
