It sits approximately 25 to 28 kilometers off the Iranian coast. The island is about 8 kilometers long and 4 to 5 kilometers wide. It is a coral outcrop that functions as a major maritime hub.

Because it provides a sea port for up to 90% of Iran's oil products, it is a site of massive economic importance. It also serves as a storage facility for up to 30 million barrels of oil. Due to the presence of the Islamic Revolutionary Guard Corps, some call it the "Forbidden Island."

The island's modern economic power comes from its connection to offshore energy. Several major oil fields lie near the island, including the Faridun, Darius, Cyrus, and Ardašir fields. Underwater pipelines transport oil from these fields directly to Kharg.

The island features several specialized terminals to manage this flow. These include the Kharg Terminal with its long T-shaped jetty, the Sea Island Terminal, and the Darius Terminal. There is also the Kharg Chemical Complex, known as the Khemco Terminal, which handles gas.

This infrastructure makes it one of the most significant oil shipment centers in the world.

Kharg Island has a complex history involving many different global powers. In the 16th century, the Portuguese Empire claimed the island. They built the Portuguese Castle to maintain military control over the Strait of Hormuz. Later, in the 18th century, the Dutch colonial empire also held influence. Dutch sailors once named the island "Delft" after a city in the Netherlands. An agent named Baron Tiddo Frederik van Kniphausen even established a free port there in 1753. He built houses in the northeast corner of the island to support this trade.

Archaeological discoveries reveal that the island has been inhabited for thousands of years. One significant find is an Achaemenid-era cuneiform inscription. This carving in Old Persian dates back to between 550 and 330 BCE. It is written on a coral rock in five lines of unusual order. The text suggests that the land was once a wilderness before water was brought to it.

Additionally, the island contains the ruins of a Christian monastery. This complex includes a chapel, a library, a courtyard, and 19 cells for monks. These sites show that Kharg was a place of religion and culture long before the oil era.

The transition to a modern oil terminal began in the 1960s. This development occurred under Mohammad Reza Pahlavi through a partnership with the American company Amoco. Significant engineering projects were completed during this time to increase capacity. For example, a 159-kilometer pipeline was finished in 1959. Later, submarine loops were laid to connect the island to other locations like Bandar Ganaveh. By 1975, the island had become the world's largest offshore crude oil terminal. This massive scale changed the island from a quiet trading post into a global industrial center.

In recent decades, the island has been shaped by political and military conflict. During the Iran-Iraq War in the 1980s, Iraqi aircraft bombed the facilities. This damage put much of the oil infrastructure out of commission for several years. More recently, the island was involved in the Iran war of 2026. During this time, the United States struck several military targets on the island.

Satellite imagery showed that Iran had reduced its oil storage in anticipation of these attacks. These events highlight how the island remains a sensitive strategic location.

Today, the island is managing a balance between industry, security, and potential tourism. While it remains a strictly guarded military and industrial zone, the government is exploring its tourism potential. In 2026, a new system for visitor permits was introduced. Tourists must now provide detailed documentation for their intended visits. They are also required to be accompanied by an approved guide at all times. This careful management allows the world to see the island's history while protecting its vital oil operations.
