Before the Suez Canal opened in 1869, ships sailing from Europe to the Indonesian archipelago came the long way around, through the Sunda Strait. The canal shortened the route dramatically - but only if you passed through the Strait of Malacca, and that meant Sabang's deep, sheltered harbor suddenly sat on a new global highway. The Dutch East Indies government recognized the opportunity and opened Sabang as a quay in 1883 under the management of the Atjeh Association. Initially a coal station for the Royal Netherlands Navy, the port quickly expanded to serve merchant vessels and handle export goods from northern Sumatra. By 1895 it operated as a free port under the Sabang Maatschappij, and in 1899 the enterprise was formally incorporated as N.V. Zeehaven en Kolenstation Sabang te Batavia. For a few decades, Sabang was a boomtown at the edge of empire, its fortunes rising with the tide of steamship traffic.

The Japanese occupied Weh Island in 1942, transforming Sabang from a commercial port into a military stronghold. Bunkers, fortifications, and gun emplacements spread across the island - remnants of which are still visible today, though most have been repurposed or reclaimed by jungle. The island's strategic value made it an obvious target. On April 19, 1944, a combined Allied naval force of 27 warships from six nations struck Sabang in Operation Cockpit, setting oil tanks ablaze and destroying aircraft on the ground. The Japanese garrison of approximately 9,000 personnel was caught off guard. A second Allied attack, Operation Crimson, followed in July, this time adding a battleship bombardment. By the time the war ended, Sabang's harbor infrastructure had been battered from both sides - built up by one occupier, hammered by the forces trying to dislodge them.

Sabang is Indonesia's northernmost administrative region, a city that technically borders the maritime territories of Malaysia, Thailand, and India. It spans five islands. Weh Island, at 121 square kilometers, holds the city center and most of the population. Rondo Island, just 0.65 square kilometers, is the northernmost point in all of Indonesia. Rubiah, Klah, and Seulake islands round out the archipelago, each smaller than the last. On Weh Island, a freshwater lake called Aneuk Laot sits in the interior, and the climate is tropical rainforest - moderate rain from February through August giving way to monsoon downpours from September to January. The island is volcanic, its terrain steep enough that all 144 kilometers of road have been paved with asphalt but public transportation remains almost nonexistent. Unlike most Indonesian cities, Sabang has no shared taxis.

Sabang's deep-sea port has become a point of quiet geopolitical significance. India and Indonesia signed a naval cooperation agreement in 2002, and Indian warships have regularly called at Sabang since. The port lies close to India's Andaman and Nicobar Islands, making it a natural node in Indian Ocean security architecture. Indonesia has granted India economic and military access to the facility, and Indian investment is flowing into the port and its surrounding economic zone. For Indonesia, the partnership helps develop a remote frontier city; for India, it provides a strategic foothold near one of the world's most vital shipping chokepoints. Sabang's Maimun Saleh Airport, meanwhile, remains a military base for the Indonesian Air Force, capable of handling ATR 72 aircraft but offering no scheduled commercial flights. The city connects to the mainland through subsidized ferry services to Banda Aceh and beyond.
