The Temple of Aset was a location on Abydos that served as the main temple of the Goa'uld Aset. The Temple was destroyed by Ra in the 1930s. (SGO: "Episode 10")
The temple sunk-relief is a copy of the well-known Helicopter hieroglyphs  from the real Temple of Seti I at Abydos, Egypt. The left hieroglyph bears resemblance to a Goa'uld symbiote.
