Egypt
A country spanning northeastern Africa and the Sinai Peninsula, widely known for the ancient civilization of the Nile valley and the pyramids at Giza.
The Great Pyramid of Giza looked nothing like today: built around 2560 BC, it was sheathed in polished white limestone from Tura — mirror-smooth, reflecting desert sun for kilometres. Medieval Cairo builders stripped most casing stones away from the 14th century onward.

Sealed honey essentially never spoils. Its water content is low (~17%) and bound to sugar, its pH of 3–4.5 is acidic, and bee enzymes add hydrogen peroxide. Microbes can't survive, so millennia-old honey is found unspoiled in Egyptian tombs.
