Where is the setting of poem ozymandias?

The setting of the poem "Ozymandias" by Percy Bysshe Shelley is a vast and desolate desert in ancient Egypt.

The poem begins with a traveler encountering a "shattered visage" in the sand, leading us to understand that the setting is a place where time has worn away the grandeur of the past. The fragmented statue and the surrounding "lone and level sands" contribute to the overall impression of a desolate and forgotten landscape.
