Depending on the assumption that buildings play the fundamental role in the formation of cities and their image, this study investigates the contribution of the Train Station to the formation of Ankara and its image in the early years of the Turkish Republic. The spatial entity of the station reflected the intended modern identity of the new state. Orienting the movement and development within its setting, the building constituted an indispensable element of the structure of the city. It acted as an immediate stimulus for the perception of the city and as a mediator for the creation of city's image. As a building of prestige, it accommodated contemporary practices and provided civilized conditions for the whole public. Consequently, the station had a significant effect on the social and spatial formation and mental re-formation of Ankara.
