What's actually there
Stone Mounds reports BD as a monumental rectangular building with slightly rounded corners, benches, symmetrically placed T-shaped pillars, twelve total pillars, and four central pillars collapsed in antiquity. Formal sources describe a likely related 15.5 x 15.5 m upper west-slope public building with seated human and griffon vulture sculpture context, but the checked formal text does not explicitly print the BD label.
