"A team of Russian archeologists working in Saqqara near Egypt’s Cairo discovered the remains of the so-called 'The White Wall' of the ancient Egyptian capital Memphis. Its Ancient Egyptian name was Inbu-Hedj which is translated as 'The White Walls.'" Source: Sputnik News.
Notes: "In ancient Egyptian art the 'colour' white represented purity and omnipotence. White was particularly associated with symbolic religious objects and tools such as those used in the mummification rituals, many of which were made of white alabaster. Alabaster was highly prized by the Egyptians because of it's beautiful shimmering white colour. As a result, it was often used for ritual items such as the canopic chest and offering vessels."

Memphis was founded during the Old Kingdom (3rd millennium BC). According to the Oxford Classical Dictionary (3rd ed. revised), "[the city], though replaced as capital under Ptolemy I, remained an important city of both Ptolemaic and Roman Egypt. At least from the reign of Ptolemy V Epiphanes (and possibly earlier) the Ptolemies were crowned according to the Egyptian rites in the city's temple of Ptah."
