The city of ancient Pelinna and the Hellenistic tomb of Petroporos are located near the EO Larissa Trikala Despite their historical value and strategic position today, the two archaeological sites remain unexploited The proposed interventions will contribute to the protection of these antiquities, to the promotion of the interconnection of the two archaeological sites and to the upgrading of the environment into a key part of the EO With the completion of the proposed act, a cultural landmark will be created in the middle of the route of the two urban centers of Larissa and Trikala, which will be an integral station of the ITI and will contribute to the development of the wider area.
