The massive Paro Rinpung Dzong or the ‘fortress of a heap of jewels’ rests on a hill above the Paro township. Built in 1646 by Zhabdrung Ngawang Namgyal, the fortress is linked to the town by a traditional cantilever bridge over the Pa Chu River. The fortress is surrounded by a paved stone path running alongside the imposing outer walls. Once inside the dzong, visitors are welcomed by the monks, beautiful architecture and the ancient frescoes, which represent unique aspects of the Drukpa Lineage of Kagyu Buddhism.
