What is the oldest stone building ever found in Africa ? @@…

The oldest known stone building in Africa is generally considered to be **the Giza Pyramids**, specifically the Pyramid of Djoser at Saqqara, which was constructed around **2630-2611 BC** during the third dynasty of the Old Kingdom of Ancient Egypt. However, if we're looking strictly at structures that can be referred to as buildings with rooms or functional space:

- **Megalithic Temples in Malta**: While not in Africa, they are worth a note for comparative age since Malta is not far from Africa. These temples date back as far as 3600-2500 BC.

- **In Africa**, predating the pyramids might be the **Tumuli of Nordic in Mauritania**, dating back to approximately **2000 BC**. These stone structures represent early architectural efforts, but they are more like burial mounds than what one might typically think of as buildings.

However, for a more specific "building" rather than tombs or temples, one might argue for:

- **The Nabta Playa site** in southern Egypt - Not a building in the traditional sense but it does feature standing stones aligned astronomically, which can be seen as an architectural endeavor, around **4800 BC** to **4200 BC**. This site has some structures; however, they are more for celestial observation than functional buildings.

Remember, construction practices from that time weren't documenting as buildings in the modern sense. Many of the oldest structures we have evidence for are primarily for religious, ceremonial, or burial purposes, and their function and status as "buildings" can be subject to interpretation, especially considering the vast chronological stretch with few surviving structures from Africa's long history.
