How Long Did it Take to Build the Great Pyramid in Giza ?
A great triva question entitled how long did it take to build the great pyramid in Giza, Egypt. We have the answer and background on the great egyptian pyramids.
The great pyramid of Giza is the oldest and largest of the three pyramids built and completed at around 2,560 BC. It’s commonly understood that the great pyramid was built for King Khufu and was the tallest man made structure in the world for over 3,800 years (now modern buildings hold that particular title). It is the only remaining monument of the seven wonders of the ancient world and is built from limestone blocks.
It is also known as the Pyramid of Cheops and it situated in the main pyramid complex at Giza although there are over 100 pyramids throughout Egypt this smaller set at Giza Necropolis is where most of the tourists go and where most of the photographs and images are taken from. Giza is situated in Cairo Egypt.
Construction
The pyramid was made from limestone blocks all 2.3 million of them that were sourced along the Nile river and brought to the site by boat. There are many theories on how pyramids are constructed an yet today we truely do not know for sure.
Secret Chambers
Inside the Pyramid are three known chambers although there may be more. There is the Kings Chamber which is line with red granite brought from Aswan some 600 miles to the south of Giza. Above the Kings Chamber are 4 other chambers with roofs made from granite.
The second chamber is the smallest and called the Queen’s chamber lined with limestone. The third is known as the unfinished chamber and is actually below ground. Egyptologists believe this was to be the buriel chamber for the King but it was abandoned as he wanted to be further up in the pyramid itself.
Photograph of the Great Pyramids Giza
If you are lucky enough to have visited these pyramids then you will surely have many photographs. Here’s one from wikipedia where you see from left to right, Great Pyramid of Khufu (the one we are discussing here), the Pyramid of Khafre and the Pyramid of Menkaure. The three smaller pyramids in the foreground are subsidiary structures associated with Menkaure’s pyramid.

The answer
So the answer to how long did it take to build the great pyramid in Giza is exactly 20 years from our research with 100,000 men involved in construction. Construction was completed in 2,560 BC over 4,500 years ago.

Im doing a project for school and was wondering how long did it take to build the other two pyramids not just khufu’s?
I was just doing an assignment on how long it took to build the great pyramids of Giza. thanks alot guys for the answer =).
I am doing a research assignment and this helped so much!! Thankyou heaps
much appreciated!!
OK, I have a thought. Today we have ships which are made of steel and what not and they brake and sink and go out of order constantly. Back in the Egyptian times, boats were made of wood. So, out of 2.3 million blocks none ever broke? None ever sank? and if some sank, would that mean that the boat that was used to move those blocks sank with them? And would that also mean that a new boat needed be constructed? And how much time would that take to build a new boat? I see a construction site today and many small bricks which we use to build with can be found lying around broken. SMALL BRICKS! and we are talking about 2.3 tons to 70 tons heavy stones. Maybe I am slow, but it makes little sense. maybe 40 years to build the pyramid? But then how long did people live back then? Seems to me that if I was a Pharaoh, I would be starting the project even before my suns birthday to make sure it is finished by his death, and then what about me? Don’t I want a pyramid for myself too???? Confusing.
I am in the 2nd grade and I really, really, really like this information and thank you for it too! I am trying to build something and needed to answer several questions about buildings and there was one I couldn’t answer which was How long did it take to build the Great Pyramid of Giza? So, thank you very much because now I can complete my question sheet. Wooowwwhooo!! Now my teacher will be proud of me.
The construction of the Great Pyramid was one hundred years. Begun in 10,490 and completed in 10,390 before the Prince of Peace entered into Egypt. With Ra and Thoth overseeing the construction…
I’m making a bucket list and someday I would really like to visit the Pyramids of Giza! This helped so so so much!! thanks!
