Nur-u Osmaniye Mosque that was built between 1748 and 1755 is one of the enormous monuments of Ottoman capital, Istanbul. The mosque is unique in terms of being first royal religious complex with Baroque style and a horse-shoe shaped courtyard. The mosque differs from the classical period of Ottoman Architecture with its architectural style and that is very interesting for construction techniques such as structural use of iron, the design of substructure and wooden pile foundations. This study focuses on the determination of structural dynamic properties of Nur-u Osmaniye Mosque which is an 18th century historic masonry monument through operational modal analysis. The experimental study have been performed on the structure was based on ambient vibration test. The paper also includes selection of the locations for instrumentation and process of data recording. The acquired data collected from the experimental study on the structure were used to identify the dynamic parameters of the structure such as main frequencies and corresponding modes. Finally, this paper gives preliminary results of operational modal analysis of the structure.
