A very cool boat ride on a muggy day --

From the ancient Egyptian perspective, Aswan is considered "Upper Egypt'. This is where its granite quarries were located. Aswan was a great trading center with one of Egypt's first boundaries with a foreign neighbor the Nubians. Many wars were fought between the two. Egyptian Kings thought so highly of the Nubians as fighters that they made them their personal Royal Guards. For a time, Nubian Kings ruled Egypt.

A brief history of the Temple --
The temple was originally located on Philae Island, a sacred place with connections to the cult of Isis that dates back thousands of years. The current temple complex was started by the 30th-dynasty pharaoh Nectanebo I and added to by the rulers of the Greek, Roman, and Byzantine periods that followed.
In the early 20th century, the complex was partially flooded after the construction of the Aswan Low Dam. Later, plans for a second dam caused UNESCO to launch a salvation project which relocated the temples during the 1960s to higher ground on neighboring Agilkia Island.
The temple complex was added to by Ptolemaic and Roman rulers up until the 3rd century AD and was a place of pilgrimage for followers of the cult of Isis long after Christianity arrived in Egypt. In fact, the temples were only closed or repurposed for Christian use in the 6th century AD, making the Philae temple complex one of Egypt's last places of Ancient Egyptian worship
