 Iconic monuments such as the Giza Necropolis and its Great Sphinx, as well the ruins of Memphis, Thebes, Karnak, and the Valley of the Kings, reflect this legacy and remain a significant focus of scientific and popular interest.Egypt's long and rich cultural heritage is an integral part of its national identity, which has endured, and often assimilated, various foreign influences, including Greek, Persian, Roman, Arab, Ottoman Turkish, and Nubian.Egypt was an early and important centre of Christianity, but was largely Islamised in the seventh century and remains a predominantly Muslim country, albeit with a significant Christian minority.
