Pyramid of Cheops
Unrivalled architectural masterpiece, technical feat, seventh wonder of the world, oldest pyramid... there is no shortage of superlatives for the Great Pyramid of Cheops. It was also the highest (today 138m) and had the greatest volume (2 521 000m3) to make the mortal remains of Cheops inviolable. Try and picture it bright white as it used to be because of its limestone covering. Portcullises obstructing the corridors protected the burial chambers. One of these gave access to the Grand Gallery. Bear in mind that there are only 300 tickets on sale each day!
