Meimoon Ghal'eh

Meimoon Ghal'eh, also known as Mehman Ghal'eh or Mobarak Ghal'eh, is a historic ruined castle located in the southern part of Qazvin, Iran. The name literally translates to "Monkey Castle," though it is sometimes referred to as "the Blessed Castle." Dating back to the 8th century, this structure is classified as a Sasanian fortress and stands as one of several ancient castle ruins scattered throughout the Qazvin region. The site covers an area of approximately 5,000 square meters and is recognized as a national work of Iran, highlighting its importance within the country's architectural heritage.

The architectural design suggests a formidable military installation originally surrounded by eight brick towers. Although the ceilings and a large central dome have since collapsed, remaining evidence points to a complex two-level structure connected by a helical staircase. A distinctive feature of the fortress is its subterranean network, consisting of three east-west tunnels linked by a north-south passage. Historians believe the main gates were situated on the northern side. The structure's layout and robust construction indicate it served primarily as a military stronghold rather than a residential palace.

Today, Meimoon Ghal'eh exists in a heavily eroded condition due to its location in an area that has remained densely populated throughout history. While the upper levels have suffered significant degradation with no ceilings left intact, the foundational elements and underground tunnel systems provide valuable insight into early Iranian military engineering. As an 8th-century fortification, it offers a tangible connection to the Sasanian era and remains a subject of interest for those studying the evolution of architecture and defense strategies in ancient Iran.
