The Grand Museum Cairo Giza will be the biggest museum in Africa and also the biggest museum in the world with just focusing on one civilization, the Egyptian, a very bald move to build but I have to admit that the two architects (one Irish and one Japanese) did it absolutely breathtaking and a marvel in a building. I have been fortunate enough to visit a few times and was always blown away by its sheer size from the statue of Ramses II the great to the pillows and columns holding it up, this is a must visit museum when in Cairo and in the future there will also be a special part all dedicated to Tutankhamun with all items on display there for the first time in history, planed to be finished in 2030.
