Meaning 'Fortress on a Heap of Jewels' ,Paro Dzong ranks as a high point of Bhutanese architecture. The massive buttressed walls that tower over the town are visible throughout the valley. It was formerly the meeting hall for the National Assembly and now, like most dzongs, houses both the monastic body and district government offices, including the local courts. Most of the chapels are closed to tourists but it's worth a visit for its stunning architecture and views.
Zhabdrung Ngawang Namgyal ordered the construction of the dzong on the foundation of a monastery built by Guru Rinpoche. The fort was used on numerous occasions to defend the Paro valley from invasions by Tibet.
