Egypt: Cairo: Dahshour Pyramids and Memphis Ancient areas.

Dahshur is listed as a UNESCO World Heritage Site, and is located on the Western Desert plateau at the edge of the cultivated plain, and along with the pyramid complexes at Saqqara, Abusir, and Giza, to its north, forms the pyramid fields of the ancient capital city of Memphis. 

It is known chiefly for several pyramids, mainly Senefru's Bent Pyramid and Red Pyramid, which are among the oldest, largest and best preserved in Egypt, built from 2613 to 2589 BC.

The Dahshur pyramids were an extremely important learning experience for the Egyptians. It provided them with the knowledge and know-how to transition from step-sided pyramids to smooth-sided pyramids. Ultimately their breadth of experience would allow them to build the Great Pyramid of Giza; the last of the Seven Wonders of the Ancient World still standing to this date.
The first of the Dahshur pyramids was the Bent Pyramid (2613–2589 BC), built under the rule of King Sneferu. The Bent Pyramid was the first attempt at building a smooth sided pyramid, but proved to be an unsuccessful build due to the miscalculations made on the structural weight that was being placed onto the soft ground (sand, gravel, and clay), which had a tendency to subside. Other calculations that were proven to be erroneous were that the blocks being used were cut in such a manner that when placed onto the pyramid their weight was not distributed appropriately, causing the angle of the pyramid to be off and achieving the name "the Bent Pyramid".

Realizing his shortcomings and learning from his mistakes, King Sneferu ordered the building of the second pyramid of Dahshur, the Red Pyramid. Once completed, the pyramid was considered to be a success, as it was a fully constructed, smooth sided, and a free standing pyramid rising to a height of 341 feet (104 meters), with an angle of 43 degrees.

The Red Pyramid's name derives from the material that was used to construct the pyramid, red limestone. This pyramid is believed to be the resting place of King Sneferu.


MEMPHIS:

During the Old Kingdom, Memphis became the capital of Ancient Egypt for more than eight consecutive dynasties. The city reached a peak of prestige under the Sixth Dynasty as a centre for the worship of Ptah, the god of creation and artworks. The alabaster sphinx that guards the Temple of Ptah serves as a memorial of the city's former power and prestige.

The Memphis triad, consisting of the creator god Ptah, his consort Sekhmet, and their son Nefertem, formed the main focus of worship in the city.
Memphis declined after the Eighteenth Dynasty with the rise of Thebes and the New Kingdom, but was revived under the Persians, before falling firmly into second place following the founding of Alexandria. Under the Roman Empire, Alexandria remained the most important Egyptian city. Memphis remained the second city of Egypt until the establishment of Fustat (or Fostat) in 641 AD. Afterward it was largely abandoned and became a source of stone for the surrounding settlements. It was still an imposing set of ruins in the twelfth century, but soon became little more than an expanse of low ruins and scattered stone.
