The existence of this palace is yet to be confirmed to be true; however, the name Ghumdan palace echoes in Yemeni history. the location of this drawing is in Sanna, Yemen, the modern-day capital of Yemen that also hosts the ancient city of Sanaa (One of many Sabaean cities).
The Sabaean script as well as the ibex drawing further indicate that this palace did exist as many real Yemeni templese today have Ibex artefacts and miniture statues all over Sabaeo-Himyarite temples and locations. The structure of this palace also resembles modren day Yemeni architecture to a small degree.
