The Mountain

Cities breathe through the spaces they cherish and the legacies they preserve. Yet, when heritage is hidden underground and communities grow around abandoned voids, the city forgets how to inhale its own memory.
In Istanbul, the Basilica Cistern—once the lifeblood of the city’s water infrastructure—remains invisible beneath the urban surface. Three issues converge: heritage is concealed and disconnected from public life, the surrounding community struggles with fragmented spaces and weakened identity, and outdated infrastructure fails to support sustainable growth.
“THE LEGACY CANNOT REMAIN SILENT BENEATH THE CITY!”
The Mountain is a radical reimagining of urban preservation, renewal, and sustainability. Rising as an organic structure above the Basilica Cistern, it transforms hidden history into a visible landmark while weaving together community life and ecological resilience. It is not a monument to the past, but a breathing extension of the city’s future.
The design addresses the three core issues through layered strategies. First, it revives legacy by revealing the cistern as a cultural and experiential anchor, reconnecting it with the Hagia Sophia and the city’s collective memory. Second, it reweaves community by integrating public spaces, housing renewal, and shared platforms that strengthen neighborhood identity. Finally, it reactivates infrastructure with a sustainable, self-water management system: rainwater collection, filtration tanks, irrigation channels, and natural purification processes are embedded within the architectural fabric. This not only ensures environmental responsibility but also demonstrates how historic water systems can inspire resilient urban futures.
In The Mountain, heritage, people, and ecology meet in one breathing organism. The project transforms preservation into activation—where history becomes visible, communities thrive, and the city learns once more to breathe with its environment.
