One of the fields that played an active role in the Westernization effect of the last period of the Ottoman Empire was architecture. Styles such as Neo-Gothic, Neo-Greek, Neo-Renaissance, Empire, and Art Nouveau were used in this area. These styles have manifested themselves in facade elements and many architectural areas. As a result of the cultural change between the 19th and 20th centuries, traditional houses began to transform into decorated and extroverted houses. As in all facade elements (such as doors, windows, decorations, and balcony railings), these changes were observed in festons and furuşs due to Western influence. The furuşs used to support the roof eaves and overhangs and the festons used to cover the rafters visible at the ends of the eaves have become visual elements that complete the facade. Feston and furuş were primarily encountered in wooden building systems, but examples of furuş made of cast iron were also encountered during the Westernization period. However, iron did not gain much ground in the Turkish House, and the use of wood, which was readily available and economical, became much more common. The presence of foreign architects from the West in the coastal cities in the last period of the Ottoman Empire caused the feston and furuş to become more diversified in these areas. This study aims to define the feston and furuş architectural elements, identify them in civil architecture examples, and reveal their contributions to the integrity of the façade. In order to examine civil architectural examples, a total of twenty-four examples located in the coastal cities of Istanbul-Büyükada and Izmir-Buca were examined. It has been observed that the festons and furuşs on the examples of civil architecture in Adalar, Istanbul, are more spectacular than the examples in Izmir and are elements that increase the monumentality of the building. The reason for this is that the Palace influenced Istanbul, was directly linked to the Westernization period, and Istanbul was the capital.
