The mortuary temple of Ramesses III is notable for its well-preserved (still colorful) decor and its depictions of the pharaoh’s defeat of the mysterious invaders known as the Sea Peoples. No one knows where the Sea Peoples came from, but Ramesses III beat them in three separate 12th century BC campaigns. The most vivid art (vultures, falcons, ankhs, etc.) in Medinet Habu can be seen on the columns and ceiling. I also like the Ramesses-shaped columns in the open-air peristyle hall, and the migdol (gate house) entrance.
