# Thandwe

Thandwe ("Thandway" in Arakanese; Burmese: သံတွဲမြို့; MLCTS: samtwai: mrui.; formerly Sandoway), historically called Dwaraddy, is a town and major seaport in Rakhine State, the westernmost part of Myanmar.

## Geography

Thandwe is very ancient, and is said to have been at one time the capital of Rakhine State, then called Arakan. The district has an area of 3,784 square miles (9,800 km$^2$). The area is mountainous, and spurs of the Arakan Mountains reach the coast. Some of the peaks in the north are over 4,000 feet (1,200 m) high. The streams are only mountain torrents to within a few miles of the coast; the mouth of the Khwa forms a good anchorage for small boats. The rocks in the Arakan Range and its spurs are metamorphic, and include clay, slates, ironstone and indurated sandstone; towards the south, ironstone, trap and rocks of basaltic character are common; veins of steatite and white fibrous quartz are also found. Between 1961 and 1990, the mean annual rainfall was 5,323 millimetres (209.6 in). Nearby Ngapali Beach is popular among tourists.

## Recent history

During the Myanmar civil war, the town was the site of clashes between the Arakan Army and Myanmar's military, with the Arakan Army taking control of Ngapali beach and several military outposts surrounding the town. According to reports, the Arakan Army seized the town's prison on 15 July 2024, with the town's remaining military battalions falling the next day and giving the Arakan Army full control of the town.
