Dhevvadhoo or Devvadū (Div: ދެއްވަދޫ) is one of the inhabited islands of the administrative division known as Northern Huvadhu Atoll (code letter: Gaafu Alifu). It is a sizeable round island located almost in the centre of Huvadhu Atoll. Some of the ancient kings of Maldives traced their ancestry to certain families of this island.
There are many Buddhist archaeological remains in Devvadū. It is likely that it was an important island in that period of Maldivian History.
A mound called “Dhevvadhoo Usgadu”, probably a large Stupa is on the north-east of the island, about 285 feet (87 m) from the shore. It is 200 feet (61 m) long, 96 feet (29 m) wide and 4 feet (1.2 m) high.
A ruin also called “Usgadu”, measuring 96 X 64 feet (20 m) with a height of 4 feet (1.2 m) is on the northwest, about 485 feet (148 m) from the shore.
Near this “Usgadu” there is another mound 116 feet (35 m) long, 52 feet (16 m) wide and 4 feet (1.2 m) high.
There is a third mound 69 feet (21 m) long 47 feet (14 m) wide and 4 feet (1.2 m) high within this area.
On the north-west there is another “Usgadu”, measuring 120 X 49 feet (15 m) with a height of 4 feet (1.2 m). It is about 385 feet (117 m) away from the shore.
None of these ancient remains have been properly investigated yet.
