Qanli Bulagh Caravanserai

Qanli Bulagh Caravanserai, also known as the Shah Abbasi Caravanserai and the Sarbaz Vatan Caravanserai, is a historical monument in Ardabil Province. It stands in Arshaq District of Meshgin Shahr County, near the border village of Qanli Bulagh (Sarbaz Vatan). The monument lies about 73 kilometres east of Meshgin Shahr and roughly 800 metres from the border between Iran and the Republic of Azerbaijan, and it is one of the remains left along the historic Silk Road. The caravanserai was built in the Safavid period, most likely during the reign of Shah Abbas. Because of its geographical position on a route used by merchants, it once held great importance for communication and trade. The monument is registered on Iran's National Heritage List under number 19016.

The caravanserai also has remarkable architectural features and is one of the few four-iwan caravanserais surviving from the Safavid era in Ardabil Province. Its rectangular building is designed with a central courtyard and iwans on all four sides, with rooms and cells around the courtyard where travellers could rest and trade goods. The complex also included spaces for keeping livestock, a loading area, and quarters for guards and the caravan members' companions. Barrel vaults, low domed ceilings in the cells, wall fireplaces and diamond-shaped brick decoration on the entrance facade are among the building's architectural features. The use of brick and lime mortar in various parts of the structure gives it a distinctive look. The caravanserai remained in use until the Qajar period and gradually lost its function in later periods; for a time, local nomads also used it as a winter settlement. Although parts of the building have been destroyed, the complex is still considered a valuable example of the region's architecture and trade history.

To visit Qanli Bulagh Caravanserai, travel from Meshgin Shahr toward Arshaq District and the Razi area, then follow the Ardabil–Germi road and the routes leading to the village of Qanli Bulagh to reach the vicinity of the building. The final stretch may be an uneven dirt road, and driving directly to the caravanserai may not be possible, so it is best to check local road conditions before setting out. Spring, with its more favourable weather, is a good time to visit this historical site. While visiting, avoid tampering with the walls, moving bricks or old building materials, writing graffiti on any part of the building, and leaving litter, so that this valuable Safavid architectural relic is preserved for future generations.
