The catalogue of Venice Architecture Biennale „Square! positively shrinking“ explores the role of high-quality urban space in enhancing the future development perspective of depopulating small towns. The articles in the catalogue investigate depopulation in both Estonian and European context and architectural means of reducing its negative effects. It also provides an overview of the main squares or streets of eight Estonian towns that were built in 2018-2020 as part of the program “Great Public Spaces”. Although the main purpose of the catalogue is to complement the Estonian exhibition in the 17th Venice Architecture Biennale, it could also serve as a guide and an inspiration to other municipalities in their own strategies of improving public space.
