Built in mid-17th century, the Rinpung Dzong ( fortress)is a prominent landmark in the Paro and houses many important old paintings and status. The richly carved wood, painted in gold, black, and the towering whitewashed walls reinforce the sense of established power and wealth. Historically the fort has been used on numerous occasions to defend the Paro valley from Tibetan Invaders. Today, it houses the district monastic body and government offices, including the local courts. It is also the venue for Paro festival, usually held on March or April.
