Arg-e Ali-Shāh (Persian: ارگ علیشاه, also known as Arg-e Tabriz, Arch of Alishah, Arg Citadel, and Masjid Ali-Shāh), is remnants of a big unfinished 14th century mausoleum and a 19th century military compound in city center of Tabriz, Iran.
The original construction was made between 1318-1339, during the Ilkhanate. Within the construction, the roof of the mausoleum collapsed and the construction was stopped afterwards. Centuries later, by the eruption of the Russo-Persian War, 1804-1813, and the Russo-Persian War (1826-1828), the compound was quickly reconstructed as a military compound. During the reconstruction of the Arg compound, a foundry factory for the manufacturing of cannons for the Iranian Army was built, as well as a military headquarter, a barrack for the troops, and a small palace was added as well to the original plan of the Arg.Samson Makintsev, better known as Samson Khan, a Qajar Iranian general of Russian origin, lived inside the citadel for years together with his wife, the daughter of Prince Aleksandre of Georgia.
