Cistern Entrance Building: a dialogue between history and modernity

A hidden treasure beneath Istanbul

In the heart of the Sultanahmet area in Istanbul, the Cistern of Theodosius represents an extraordinary example of Byzantine hydraulic engineering dating back to the late 5th century. This ancient reservoir, built by the Emperor Theodosius II, spans an area of 42.5x42.5 meters and is characterized by a dome roof supported by 32 marble columns with Corinthian capitals. Thanks to one of the most significant contemporary architecture projects, designed by Cafer Bozkurt Architecture, the surrounding space has been completely transformed, enhancing the cistern itself and the urban context in which it is located. The intervention has created a bridge between the past and the present, making a unique historical heritage visible and accessible.

A project that reveals hidden heritage

The redevelopment has allowed to rediscover and enhance a buried historical heritage beneath the modern urban fabric. The removal of the buildings that stood above the cistern revealed a small public space, transformed into a square that celebrates the historical stratification of Istanbul. The geometry of the cistern has been reproduced on the surface with details that reflect its shape and materials, creating a visual and tactile dialogue between what is visible and what is hidden.

A square between history and contemporaneity

The new square, called Piazza della Cisterna, is organized around a reflecting pool that recalls the water of the underlying cistern. The pool marks the transition between the urban space and the access to the historic site, offering a fluid and meditative transition experience. The nearby Pierre Loti Plaza, in continuity with the geometric order of the cistern, creates a gathering and connection area, enhancing spatiality through the presence of existing trees and the evocation of the ancient axis of Pierre Loti Street.

A transparent and respectful entrance

The new entrance building is a contemporary structure made of glass and steel, designed to integrate seamlessly without interfering with the historical character of the area. Its dimensions and materials have been carefully chosen to harmonize with the surrounding historic buildings, such as the Mosque and the Tomb of Köprülü Mehmet Pasha. The building houses ancillary functions such as a cafeteria, services, and technical spaces, with a block of opaque wood that maintains visual order and discretion.

Awards and recognition for excellent redevelopment

This urban redevelopment project has received significant recognition for its ability to balance innovation and preservation. In 2016, it won the "Design/Preservation Category Award" at the XV National Architecture Exhibition, while in 2020 it received the "Committee Incentive Award" from the Arkitera Architecture Center. Its ability to create a public space that enhances history and offers a new experience to visitors makes it a virtuous example of how architecture can preserve and transform cultural heritage.
