The Ramesseum is an ancient temple complex located on the west bank of the Nile River in Luxor, Egypt. It was built during the New Kingdom period, specifically during the reign of Pharaoh Ramesses II (also known as Ramesses the Great), in the 13th century BCE.

The Ramesseum was dedicated to the worship of the god Amun and to the Pharaoh Ramesses II himself. The complex covers an area of approximately 42 acres and includes several structures, including a large pylon (a monumental gateway), a hypostyle hall (a hall with columns), several courtyards, and the main temple itself.

One of the most notable features of the Ramesseum is the large statue of Ramesses II that once stood in the main temple. The statue was carved from a single piece of limestone and weighed around 1000 tons. Unfortunately, the statue was broken during an earthquake and now lies in pieces on the ground.

Another notable feature of the Ramesseum is the "Hall of Kings," which contains a series of relief sculptures depicting various Pharaohs. Additionally, the Ramesseum has several chapels and smaller temples dedicated to various gods and goddesses.

Today, the Ramesseum is a popular tourist attraction and is considered to be one of the best-preserved temple complexes from the New Kingdom period in Egypt. The site has also been the subject of extensive archaeological research, with ongoing excavations revealing new insights into the history and culture of ancient Egypt.
