This watchtower, which once guarded Trongsa Dzong from internal rebellion, stands impressively and provides visitors and insight into historical significance of Trongsa in Bhutan’s history. It has four observation points resembling Tiger, Lion, Garuda, and Dragon. This watchtower (ta dzong) overlooking the dzong now houses an excellent museum. The five floors of displays focus on Buddhist art and royal memorabilia, including such varied treasures as the 500-year-old jacket of Ngagi Wangchuk and the football boots used by the teenaged fourth king. You can drive here or walk up a steep staircase from town. The most sacred religious item is a copy of the Padma Kathang, a biography of Guru Rinpoche written by his consort Yeshe Tsogyel. There are two lhakhangs inside the Ta Dzong; the Gesar Lhakhang is dedicated to the 19th-century penlop of Trongsa, Jigme Namgyal.
