1. The Colossi of Memnon are two massive statues of Pharaoh Amenhotep III, constructed around 1350 BCE, located in Luxor, Egypt. Each statue stands at 18 meters (60 feet) in height and weighs around 720 tons. The statues were constructed with quartzite stone and were a part of the massive temple complex, which existed in the ancient city of Thebes, located on the west bank of the Nile River. The statues are surrounded by agricultural fields and small villages and have been a popular tourist attraction for centuries. One of the unique features of these statues is that they are known to produce a musical sound at dawn, caused by the changes in temperature and humidity. This phenomenon has been mentioned by several ancient writers, including Strabo and Lucian, and it was believed to be the voices of the dead speaking to their pharaoh.
