This article explores the spatial dimensions of Athens' carnival and their change in the course of a century. It is based on two polarities: first, that of the old city and the new city, which was related to the contrast between traditional and modern culture in the celebration of carnival. Both the old city and traditional culture were increasingly undervalued and denounced until the inter-war years, when nostalgia for old places and practices developed. The second major contrast is that between the centre of Athens and its periphery. There was a strong tendency towards the concentration of carnival events and crowds in the centre of Athens until the 1900s. This development is correlated with the reinforcement of the middle class and its cultural hegemony. A new autonomy of the neighbourhoods of the popular classes in the inter-war period did not result in the revival of popular carnival culture.
