The article asks whether the divided town Cieszyn-Český Těšín can be considered a joint “living space” in the shadow of the COVID-19 pandemic. It evaluates the impact of the pandemic on various aspects of the daily lives of the inhabitants and institutions of both parts of this divided town. Three main dimensions of cross-border integration were studied: cross-border flows, cross-border structures/institutions, and the feeling of togetherness, which represents an ideational dimension of cross-border integration. The research was based on studying narratives covering border closures in the divided town, the analysis of cross-borderness of existing Facebook groups acting in both parts of the divided town, and the results of an extensive questionnaire-based survey among its inhabitants. The border closures restricted cross-border flows, which hit cross-border commuters and damaged the quality of this divided town as a living place because it introduced uncertainty. However, the health crisis also showed the high level of mutual interconnections between the local inhabitants and a functional cross-border civic society. The local people and politicians tend to perceive the divided town as a joint living space. The level of cross-border integration highly exceeds the one usual in the “new EU.”
