One of the main attractions in Paro is the Paro Dzong. It was built in 1646 and now houses government offices and religious institutions, as do all the dzongs (forts) currently. You'll cross a traditional wooden bridge on the way to the dzong. On the hill above the dzong is the National Museum, which used to be a watchtower (ta dzong) for the dzong. It contains a collection of art, costumes, relics, religious paintings, handicrafts, and national stamps.
