Arg of Tabriz (Persian: ارگ تبريز, also known as Arg Alishah, Arg-e Alishah, Arch of Alishah, Arg Citadel, and Masjid Ali-Shāh), is the remnants of a big unfinished 14th-century mausoleum and a 19th-century military castle and barrack in city center of Tabriz, Iran.
The original construction was made between 1318 and 1339, during the Ilkhanate. Within the construction, the roof of the mausoleum collapsed and the construction was stopped afterward. 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.
