Oh, I already read about this somewhere... oh, here:http://i-cias.com/egypt/kharga03.htm
This temple, named after the town that once existed here, is unique for Egypt in one respect. It is by far the largest and finest of temples from Egypt's 200 years under Persian rulers. It was King Darius 1 of the 6th century BCE who ordered it built, and dedicated to Amon. The temple was adorned by rulers over the following centuries, but the original style was always respected.
Today it is not available for closer inspection, as the main structure is swathed in scaffolding. It is planned to be relocated to a new location, close to the Bagawat Necropolis, but this will not be realized for many more years.
Should you be allowed to enter the area (it is guarded by tourist police, no tickets are sold) the kiosk in front of the main entrance (upper photo) is part of what was an avenue of sphinxes. The interior (visible through the gates) is noted for its beautiful capitals.
