Qasr Ain es-Sil is a modest Umayyad-era farmhouse located approximately 1.75 kilometres northeast of the Azraq Fort in Jordan. Dating back to the 8th century CE, this structure exemplifies the rural architectural style of the period. The farmhouse comprises four rooms constructed from local stone, reflecting the Umayyad emphasis on integrating buildings with their natural surroundings. Adjacent to the main building is a small bathhouse, or hammam, indicative of the importance placed on hygiene and ritual purification in Islamic culture.  

The presence of both residential and bathing facilities suggests that Qasr Ain es-Sil served as a self-sufficient agricultural estate, possibly supporting local farming communities or serving as a retreat for urban dwellers seeking respite in the countryside. Its proximity to Azraq Fort implies a strategic location, potentially benefiting from the protection and trade routes associated with the larger military installation. Today, the remains of Qasr Ain es-Sil offer valuable insights into the daily lives and architectural practices of rural communities during the Umayyad period in Jordan.
