Garabaghlar Mausoleum is a historical and architectural monument located in the Karabakhlar village of Tərtər region in Nakhchivan, Azerbaijan. This magnificent mausoleum dates back to the 12th-14th centuries, serving as a testament to the architectural artistry of that period. It is a part of a complex that once included a mosque and a madrasah, which have since been ruined. The mausoleum is known for its cylindrical tower-like construction, which is typical for the architectural style of Nakhchivan mausoleums. The structure is adorned with intricate geometric and vegetative ornamentation, showcasing the skill of the craftsmen of the time. The mausoleum is capped with a stunning dome that has largely collapsed, yet the remnants still demonstrate the intricate brickwork that would have formed the basis of this dome. Over the years, the Garabaghlar Mausoleum has sustained damage due to natural deterioration, but in recent years, restoration work has been undertaken to preserve its historical value. This site is an essential part of the cultural heritage of Nakhchivan and offers valuable insights into the history and architecture of Azerbaijan.
