Khan Mirjan — Wikipedia

The Khan Mirjan (Arabic: خان مرجان) is a building in the souk of Baghdad, Iraq. It was built by the Jalayirid governor of Baghdad, Amin al-Din Mirjan in the 14th century originally as a caravanserai, an inn for traveling merchants, with a large center hall that was 13 metres (43 ft) high. It features crenelated arches of brick, as well as perforated windows. The building was reputedly in a state of disrepair for over two centuries, with waist-high flood water from the Tigris standing in the famous hallway. By the mid-1980s, the building had been restored and was in use as a restaurant.
