Eskisehir Ziraat Bank Building is one of the branch buildings which was designed by Giulio Mongeri (1873-1951) in Anatolia during the Early Republican Period. The building’s design has features of the First National Architectural Movement and it is one of the symbol buildings of urban identity. According to correspondence from 1906 and 1907, Ziraat Bank (established in 1888) requested land for the new branch building in Eskisehir. Construction started in 1928, and the building was opened on the seventh anniversary of the Republic’s establishment on 29th October 1930. In 1978, the company requested to demolish the building. In 1979 it was registered as Immovable Cultural Property to be Protected since it belongs to the pre-1930 Republic Era. In 2005, it was designated as Protection Category I (one). The building underwent various interventions during the time However, it is hard to follow these because of the lack of any restitution project. The study aims to reveal the original architectural and artistic elements of the building by tracing the changes in the structure and comparing it with other buildings, according to documents, reports, drawings, and photographs received from archives. In this study we evaluate the elements of Mongeri’s Eskisehir Ziraat Bank Building’s design that reflect the movement’s features and we also consider the place it held in its era. The results of our study show that Mongeri used the features of this movement in the arrangements of the facades, and also in the entrance and customer hall using Ottoman elements such as Bursa arches, muqarnas, hatayi, and so on, and all these elements can be seen today. Although the building’s holistic value has been reduced because of changes in the entrance door as well as the non-existence of original furniture, the addition of a new interior door, and modifications related to technological improvements, the building still has the characteristics of the First National Architecture Movement.
