The Red Pyramid, also known as the North Pyramid, is a famous ancient Egyptian pyramid located in Cairo, Egypt. Built by Pharaoh Sneferu around 2600 BC, it stands out for its reddish hue due to the red limestone used in its construction. It is the third largest pyramid in Egypt and is believed to be the first successful attempt at building a smooth-sided pyramid. Visitors can explore its interior chambers, which have unique features like a corbelled roof and a ventilation system. The Red Pyramid is a must-see attraction for history buffs and pyramid enthusiasts alike.
