Chehel Sotoun Palace, also known as Forty Columns Palace, is an emblematic historical edifice located in Isfahan, Iran, within a vast and stunning Persian garden. Constructed in the mid-17th century during the Safavid era, it served as a reception hall and entertainment pavilion. The name 'Chehel Sotoun' is inspired by the twenty slender wooden columns supporting the entrance pavilion, which, when reflected in the front pool, appear to be forty. This hall is adorned with a variety of frescoes, miniatures and ceramics that display scenes from historical events, showcasing the artistic and cultural achievements of the Safavid period. The ceiling of the palace, with its intricate wooden inlay work and exquisite paintings, adds to the grandeur of the architecture. The Royal Hall is particularly notable for its mirrored interior, and the palace is surrounded by a classical Persian garden, which adds to its serenity and beauty. Chehel Sotoun holds a prominent place in Iranian history and is recognized as a UNESCO World Heritage Site along with other monuments in Isfahan.
