The Nyoum Pyramids in Egypt are some of the most significant architectural wonders in the world. They are a compound of pyramids that are located in the city of October 6, which is just outside of Cairo. The Nyoum Pyramids are one of Egypt's most popular tourist attractions and are visited by millions of people every year.

The Nyoum Pyramids are believed to have been built during the reign of Pharaoh Sneferu between 2613 and 2589 BC. Sneferu was the ruler of the Fourth Dynasty and was known for his massive building projects. He is believed to have commissioned the construction of three pyramids in the Nyoum compound.

The largest pyramid in the Nyoum compound is the Pyramid of Sneferu. It is also known as the Bent Pyramid because of its unique shape. The pyramid is about 100 meters high and has a base that measures 188 meters. The pyramid is called the Bent Pyramid because of the change in angle that occurs halfway up the structure. The lower section has a steep angle of 54 degrees, while the upper section has a shallower angle of 43 degrees.

The second pyramid in the Nyoum compound is the Red Pyramid, which is the third-largest pyramid in Egypt. It is called the Red Pyramid because of the red limestone that covers its exterior. The pyramid is 105 meters high and has a base that measures 220 meters. It is considered to be the perfect pyramid because of its symmetrical shape and angle of inclination.

The third pyramid in the compound is the Pyramid of the Black Pyramid. It is believed to have been built for Sneferu's wife, Queen Hetepheres. The pyramid is smaller than the other two pyramids and is only about 30 meters high.

The Nyoum Pyramids are an important part of Egypt's rich cultural heritage. They are part of the UNESCO World Heritage Site of Memphis and its Necropolis - the Pyramid Fields from Giza to Dahshur. The pyramids are a testament to the architectural and engineering skills of the ancient Egyptians and continue to inspire wonder and awe in those who visit them.
