According to legend, when the lamas assembled in about 1549 to select a site for a monastery, a big white bird rose suddenly in the air and settled on a spur of a hill. This was interpreted as an important omen, and the hill was chosen as the site for a monastery and for Jakar Dzong, which roughly translates as 'castle of the white bird'. The Zhabdrung's great-grandfather, Ngagi Wangchuck, founded the monastery.
Jakar Dzong is in a picturesque location overlooking the Chokhor valley. The current structure was built in 1667 and has a circumference of more than 1500m. Its official name is Yuelay Namgyal Dzong, in honour of the victory over the troops of Tibetan ruler Phuntsho Namgyal. The utse (central tower) is unusually situated on the outside wall, so there is no way to circumambulate it. A walled passage leads from the dzong down the hill to a nearby spring – a feature that ensured water could be obtained in the event of a long siege.
The approach to the dzong is made on foot along a stone-paved path. The entrance leads into a narrow courtyard surrounded by administrative offices. The utse is on the east side of the courtyard, and beyond that is the monks' quarters and the district court. At the west end of the dzong is a slightly larger courtyard surrounded by administrative offices. Behind here, outside the main dzong, is a half-round ta dzong (watchtower).
Even if the chapels are closed, it's a worthwhile climb for the views of the Chokhor valley from the front courtyard.
