Due to the historical significance of the site, the project reinterprets Marvi Plaza by extending the spatial continuity of the courtyard of Golestan Palace toward its western gate and the forecourt of Shams-ol-Emareh. To frame a clear visual axis toward this historic ensemble, a gently sloping platform was designed, incorporating a central depression that creates an inviting public gathering space while also providing informal seating. This sunken form preserves uninterrupted views toward the palace complex and reinforces the site's visual connection with its historical context.
The geometry is mirrored below ground to form a bowl-shaped structural system. This inverted form stabilizes the structure through its geometry alone, eliminating the need for internal columns and creating a large, unobstructed interior space. The resulting underground hall is envisioned as a gallery for exhibiting photographs, manuscripts, and artworks related to Golestan Palace, enriching visitors' understanding of the site's cultural and historical heritage.
