Transbordering Laboratory is a research on and between European cities that are divided by borders. We aim to address the idea of forming new realities in such cities and areas. Hard borders became an issue again with the rise of nationalism and the pandemic, especially for citizens in the border territories. Many of the border cities started to forge a common life since the 1990s and reinvented themselves as unified towns. Our aim is to gradually form a network of these towns in order to share experiences and creativity.
