Initiated by the Klassikstiftung Weimar, the “Green Laboratory” was built in 2021 on the foundation walls of the former Tempelherrenhaus in Weimar's Ilmpark – providing a meeting place that invites visitors of the park to linger for a while and aims to create a new access to the park and nature. In a total of four films, the project is portrayed and documented from its initial design, through the construction phase, to its eventual operation.
