Visit the Ta Dzong. This watchtower, which once guarded Trongsa Dzong from internal rebellion, stands on a promontory above the town. It was built by Chogyal Minjur Tempa, the 1st Governor of Trongsa in 1652. It has four observation points representing a tiger, lion, garuda, and dragon. A visit to this former watchtower provides visitors with an insight into the significance of Trongsa in Bhutan’s history. As of date, the Ta Dzong of Trongsa is the most fascinating museum in the kingdom.
