Trongsa Province occupied lands in central Bhutan corresponding somewhat to modern Trongsa District, although the power of the Trongsa Penlop extended far beyond his own realms, covering the entire east of Bhutan. The province was administered from the Trongsa Dzong in the town of Trongsa, and its ruling governor was known as the Penlop of Trongsa, or Tongsab.[1][2][3]
