New evidence proves that the ancient Egyptians constructed the Great Pyramid at Giza by transporting 170,000 tons of limestone in boats. It has long been known that the rock was extracted eight miles away in Tura and that granite used in the monumental structure was quarried 533 miles away in Aswan.

They arrived in their thousands. Hardened by months of war with ferocious natives, near-starvation and exotic diseases, Hernan Cortez and his Spanish army marched into the great city of Cholula expecting a fight. But this was a sacred city. Instead of investing in weapons, its inhabitants built temples; it was said they had a holy pyramid for every day of the year. After such generosity, their gods would surely protect them.

Three ancient pyramids have been discovered in the Antarctic by a team of American and European scientists. Two of the pyramids were discovered about 16 kilometers inland, while the third one was very close to the coastline. An expedition to the bizarre structures should answer the intriguing question whether they are artificial or natural. The first reports about the pyramids appeared in western mass media last year.

Do scans that have found "thermal anomalies" suggest secret tombs and unknown treasures hidden within Egyptian pyramids?

An ‘impressive’ heat difference between the blocks has been found at four of Egypt’s pyramids, including the famous Great Pyramid of Giza, researchers say. The finding has been uncovered by a project aiming to penetrate the secrets of the pyramids.

Two weeks of new thermal scanning in Egypt’s Giza pyramids have identified anomalies in the 4,500 year-old burial structures, including a major one in the largest pyramid, the Antiquities Ministry announced Monday. Antiquities Minister Mamdouh el-Damaty and technical experts working on the project showed the higher temperature being detected in three specific adjacent stones at the bottom of the pyramid in a live thermal camera presentation to journalists.

Think that the Ancient Egyptians only built pyramids in Egypt? Think again. The Nile Valley continues south deep into Sudan, and the ancient Kingdom of Nubia is home to more pyramids than 200 pyramids dating from 800 BC.

On his last full day in space aboard the International Space Station (ISS), NASA astronaut Terry Virts at last captured a truly iconic shot of one of the “Seven Wonders of the World”.

A circular stepped pyramid built more than 2,000 years ago has been discovered in eastern Bolivia, local media reported. Danilo Drakit, the coordinator of the archaeology project in the government of Bolivia's department of Santa Cruz, was quoted as saying that the pyramid is made of three circular sections of different diameter.

Skyscrapers are the traditional small-footprint solution for growing square footage in big cities, but what are developers to do in growing places like Mexico City where new building construction is limited to just ten stories tall?

A Martian pyramid, a modular beehive and a three-tiered Acropolis have made the final cut in the MakerBot Mars Base Challenge. Run by Thingiverse and launched in conjunction with the 3D printer maker and Nasa's Jet Propulsion Laboratory, the challenge has been open since 30 May and clocked up 227 applications. The three winning entries will each be awarded a MakerBot Replicator 2 Desktop 3D Printer in order to help them fully explore their designs for Martian abodes.

Alien pyramid-building theories take a blow as a new study shows Egyptians may have used water to help move the massive stones.
