Art historian Suvi Vepsä and artist Egle Oddo have been collaborating within Vepsä’s doctoral research since 2021. Their joint action started during the realisation of an Evolutionary garden on the occasion of the XXV Mänttä Art Festival. The garden is still part of the public domain of the City. Vepsä and Oddo have been observing the changes and interactions in the garden for four years. In Aleksanterin Linna they present a cross-section from their archives, including notes, images and raw materials that have been emerging during their research, as well as new material collected by Vepsä during their one-month stay in the Serlachius Residency.
