Mentioned in the Hudud al-'Alam as a good source for pearls around 982 AD, Khark was visited by the French traveller Jean de Thévenot in 1665, who recorded trade at the time with Isfahan and Basra.

[5] The first archaeological evidence of human occupation on Khark island was reported by Captain A. W. Stiffe in 1898, with studies published about his discoveries by F. Sarre and E. Herzfeld in 1910.

[10] There are also ruins of a coarse stone temple on the island measuring around 7.5 m (25 ft) square with a plastered altar for fire in the centre.

[2] On November 14, 2007, a cuneiform inscription dating back to Achaemenid era was discovered on Kharg Island in Old Persian.

[14] The Iranian dialect of the Persian settlers of the Achaemenid period may have in turn been the ancestor of the Khargi language, with Borjian adding that "there is no contradicting evidence to make this hypothesis implausible".

[15] The 17th-century French traveller Jean de Thévenot noted the presence of qanat (i.e. kariz) on the island that would have provided ancient irrigation.

[2] The island appears with a SAM radar installation on it in the Sega Genesis flight simulator F-15 Strike Eagle II in the Persian Gulf mission map.
