New Findings on Hagia Sophia Subterranean and its Surroundings

BIZANTINISTICA. Rivista di studi Bizantini e Slavi - Fondazione CISAM, 2010

This article is covering the findings of our researches at the subterranean of Hagia Sophia (subterranean structures, water supply, drainage and ventilation lines, wells and cisterns. The Topkapı Palace Museum , Istanbul Archaeology Museum (acropole and I. Hill) Hippodrome areas were also included in our later researches. All of the mentioned structures are measured by architects and scaled plans are included in this article.

Discovery and documentation of the Underground structures of Hagia Sophia

Hypogea, 2023

Hagia Sophia, an iconic world known monument of Late Roman-Early Byzantine architecture, is located at the heart of Istanbul and holds great importance in world architectural history. To fully comprehend its significance, it is crucial to examine the structure from all angles. The underground structures of Hagia Sophia have been investigated many times before. The first exploration and documentation attempt took place by cavers in 1986. Later, extensive studies were carried out by different caving groups and a total of 548 m of underground passages were mapped and documented. In February-July 2020, our project began with the aim of creating a 3D documentation of Hagia Sophia's underground structures. The project was led by the faculty members of the Department of Architecture at Fatih Sultan Mehmet University and Galeri Cave Research Group. Laser scanners such as Leica Blk 360 and Faro Focus 150 S were used to carry out the documentation process. Mapping of the newly discovered tunnels and the ones with level differences from the existing tunnel system was done using traditional methods due to the very narrow passages. The project led also to the discovery, mapping, and photography of new tunnels and underground structures. Consisting of 388 meters. Thus, total length of underground structures of Hagia Sophia reached to 936 meters.

Digital documentation of three largest subterranean structures of Hagia Sophia: The passage under the esonarthex, the vaults under the atrium and the hypogeum

Technical Annals, 2023

The terrestrial scanning project of Hagia Sophia's subterranean structures took place in 2020. This field study enabled the creation of a threedimensional point cloud model capturing the underground tunnels and structures. Subsequently, in 2022, a more detailed documentation of the older hypogeum within Hagia Sophia was conducted. This study particularly focused on the three largest subterranean structures on the site. The first of these is the passage beneath the esonarthex, delineating a structural transition between the Theodosian and Justinian periods, spanning from the fifth to the sixth centuries. Notably, the discovery of a previously unnoticed column base on the floor of this structure prompted an update to the plan of the Theodosian atrium. The second focus lies on the vaults beneath Justinian's atrium, requiring an architectural visualization update since Schneider's documentation in 1941. These subterranean structures define the boundaries of the no longer physically existing Justinian atrium, and the debris within them awaits excavation to provide further insights. The last structure examined is the hypogeum dating back to the 4th century. This structure underwent a more detailed redocumentation following a partial clean-up and has been digitally visualized.

The Story of the Architectural Documentation of Hagia Sophia’s Hypogeum

Open Archaeology

Hagia Sophia’s hypogeum is a group of subterranean Roman tomb structures located in the area between the northeastern side of the structure and the imaret (“soup kitchen”) of Hagia Sophia. Consisting of three chambers connected by a passage, the hypogeum is dated to the fourth century and older than the current Hagia Sophia. The story of the architectural documentation of the hypogeum is also interesting. As a matter of fact, exposed findings during the museum research still contribute to the dating studies of the structure. The first digital architectural visualisation of the space was made in 2020 within the documentation of the subterranean structures of Hagia Sophia. After the partial cleaning of the inner space at the end of 2021, a relatively more favourable environment allowed for its visualisation. This study presents the most recent architectural documentation of the hypogeum carried out, the first reconstruction plan proposal, and a virtual superposition of the structure w...

Diegeseis on Hagia Sophia from Late Antiquity to Tenth-Century Byzantium, Byzantinoslavica 73 (2015)

In the Byzantine era, Hagia Sophia was mentioned and extolled in a large number of texts, ranging from the rhetorical to the historiographical and hagiographical. This article provides an overview and discussion of the relatively few early and middle Byzantine narratives about Hagia Sophia, which attest to the various roles it could assume in imagination and ideology. It concentrates on narrations dating from the ninth and tenth centuries and argues that their writing was dictated by such different considerations as the clash between the emperor and the patriarch, intra-ecclesiastical conflicts, and the idea that the age of holiness and piety had not ended. Particular attention is paid to the Narrative about the Construction of the Temple of the Great Church of God which is called Hagia Sophia and the circumstances of its creation. This must be placed in the last decades of the ninth century and should be associated with the opposition of the supporters of the Patriarch Ignatios to Patriarch Photios and his circle.

The Wells, Subterranean Passage, Tunnels and Water Systems of Hagia Sophia in Istanbul

2006

In November 2005, a survey was begun of the wells in and around Hagia Sophia Church in Istanbul. The long-term goal of the survey is the understanding of the function of the tunnels and the water systems used for Hagia Sophia and its surroundings during the Byzantine and the Ottoman periods. Alternate research methods, such as geophysical research, will be used in future surveys. The 2005 survey examined the channels that run from under the narthex and continue northwards and the southwards of the building as well as channels that run towards the atrium, hippodrome, and garden in the north. The survey resulted in the first photos of the well-bottoms in the history of Hagia Sophia.
