This article draws on ethnographic fieldwork and interviews to explore young minority men's relation to school and city space in Helsinki from the perspective of their everyday experiences of racialisation in public spaces. The article uses the concept of 'power geometrical' relations of space by drawing on several research traditions, including youth and masculinity studies, studies on social space, racialisation and ethnicity, and human geography. The evidence shows the school to be an important site of local and national power geometry (Massey, D. [1994]. "Space, Place and Gender." Cambridge: Polity Press), in which 'informal' and 'physical' spheres are dominated by peers and connect to streets and public spheres (Gordon, T., J. Holland, and E. Lahelma. [2000]. "Making Spaces: Citizenship and Difference in Schools." Houndsmills et al. London: MacMillan Press Ltd). The article shows how young minority men knew their place both in narrow local power geometries, and within the wider city and school spaces, exploring how they formed their own lived spaces (Lefebvre, H. [1991]. "The Production of Space." Oxford: Blackwell), claimed their spaces and marked their spaces with diverse tactics. Some tactics were socially open, such as making friends; some were very mobile, such as claiming their own urban spaces by mobility, or marking and 'hanging around'; and some involved big groups of friends, crowds, defence and embodied accounts.
