During the Covid-19 pandemic, lockdowns, and the unfolding of mobility restrictions throughout Europe, the question of accessibility came to the forefront of academic and political discussion. That became most evident for population groups that came to be known as high-risk, meaning mostly the elderly and people with specific medical conditions. At a societal level and mainly due to ageing, a significant proportion of European populations fell automatically within this category and, in that sense, cities were also 'high risk.’  At the individual level and scale, varying levels of accessibility have determined the quality of life for most urban populations, and more so for those belonging to high-risk groups, for almost two years. Overall, social distancing measures highlighted the need for cohesive and compact communities and neighborhoods, and in this context, concepts promoting locality and proximity like the 15-minute city (15MC) gained significant momentum. Although Paris adoption of the goal gained significant attention, the agenda is put forward by numerous cities around the world, for example those belonging to the C40 network: https://www.c40.org/cities/.
