PHİLLİPP HOLZMAN ŞİRKETİ’NİN OSMANLI TOPRAKLARI’NDAKİ İNŞAAT FAALİYETLERİ

The 19th century marks a period of restructuring for the Ottoman Empire, initiated by the reforms of Sultan Mahmud II (r.1808-1839) and concluded during the reign of Sultan Abdulhamid II (r.1876II (r.-1909)).This century-long process of renewal transformed the architecture of Ottoman cities.New building types such as ministry (nezaret) buildings, schools for the new educational system (Rtiye, li Mektep, Dar-l Fnun, dadi), government offices (hkmet kona), railway stations, factories (Fabrika-i Hmayun), dry docks, wharves, and infrastructure like railway bridges and tunnels were constructed using new materials (cast iron, steel after 1893, large-scale glass, and concrete) and construction techniques (ironsteel frames, reinforced concrete).The second half of the 19th century and the early 20th century also witnessed a period of close collaboration between the Ottoman Empire and Europe in the fields of engineering and construction.During this period, European construction companies operating in Ottoman territories introduced modern construction techniques and engineering approaches to the region, paralleling developments seen across Europe, Africa, and the Americas.Among these companies, Philipp Holzmann stood out for its significant contributions, to both large-scale infrastructure projects-such as bridges, railways, tunnels-and architectural works like railway stations, schools, hospitals, and mausoleums.This article analyzes the activities of Philipp Holzmann in the Ottoman Empire to understand the firm's role in transferring modern engineering expertise to the region.It also evaluates the company's efforts to adapt its projects to local traditions and conditions, as well as its contributions to Ottoman modernization.By examining its portfolio, ranging from railway construction to symbolic structures like Haydarpaa Railway Station and the Mausoleum of Sultan Mehmed V (r.1909-1918), this study presents the innovations introduced by Philipp Holzmann and the legacy it left on the Ottoman construction practices.
