GPR Analysis Of Sultan Ahmed III Library (Enderun) In Topkapi Palace, Istanbul Before Restoration

Abstract

"Topkapı Palace was constructed between 1460 and 1478 by Sultan Mehmed the Conqueror. The Neoclassical Enderûn Library, also known as Library of Sultan Ahmed III, is situated directly behind the Audience Chamber in the centre of the Third Court of the Topkapi Palace in Istanbul. The Neo-classical Enderûn Library was built in 1718. To investigate the deformation conditions of this Library by non-destructive examination with the GPR-CX (Ground Penetrating Radar – Concrete Exploration) method was carried out. Mainly GPR-CX method was improved for investigate modern concrete walls and systems, as well as the high resolution and speed with non-destructivity made the system suitable for ancient buildings. In this study 2.3 GHz HF antenna was conducted with a 100×100 cm grid area to all the walls of Library, lead water pipes, vaulted base etc. were discovered. In addition the metal clamps of wall connections were also found and contributed to the static studies. By courtesy of non-destructive GPR-CX method, many unknown data were put forward about Library, which were constructed at 1718 AD."
