This special issue of Ehituskunst brings to the surface some of the rich and diverse research material that architect and pro- fessor Jan Verwijnen left to EKA Tallinn's architecture faculty when he passed away in 2005. The project does not intend to be a collection of personal memories but rather hopes to engage some key figures of Verwij- nen's professional network to reflect upon his work, specifically on the ideas and projects which emerged in the time he was most active in Finland and Estonia. By reconsidering the debates Verwijnen was engaged in, several authors will discuss how ideas and projects of that period have been further developed, con- firmed, falsified or recontextualised – ultima- tely bringing to the fore the relevance of these ideas for architectural discourse and practice today. The special issue was put together by Panu Lehtovuori and Klaske Havik.@en
