Athens, Greece
City population: 2790721
Duration: 2013 – ongoing
Implementation status: Ongoing
Scale: Micro-scale: District/neighbourhood level
Project area: unknown
Type of area: Public Greenspace Area, Central Business District / City Centre
Last updated: October 2021

"The main idea of the project is to join the two parks at the end of the intervention (Pedion Areos and Lofos Likavitou) with a green mass that will flow all along the intervention, bringing back the greenery to an area that used to be a green zone in the outside of the old Athens walls.That green corridor is formed by: (1) the existing trees preserved; (2) the new trees added; (3) a continuous floor all along the project with a pattern that is an abstraction from olive tree branches; (4) The artificial activity/bioclimatic trees they create" (Ref 1).

Project objectives

The main idea is to join the two parks at the end of the intervention (Pedion Areos and Lofos Likavitou) with a green mass that will flow all along the intervention, bringing back the greenery to an area that used to be a green zone in the outside of the old Athens walls and creating a green corridor that joins the old Athens with the new Athens (Ref 1). The project also aims at reducing and offsetting carbon emissions in order to achieve a zero-carbon balance, create new spaces for public activities and reduce the harsh climatic conditions of the city (Ref 4).

Implementation activities

As the project is yet to be implemented, followings are the plans of the implementation. Based on the results of a deep analysis of the area the authority has obtained a series of outputs that have guided the activities that they are developing: flows analysis, sun-incidence studies, building uses, full-empty contrasts, demand-offer of activities, existing vegetation mass, existing and foreseen public transportation, transportation and communication nodes, natural-artificial light, etc. Sustainable integration is the key concept at this point. They are planning to preserve the existing trees, add new trees, make a continuous floor all along the project with a pattern that is an abstraction from olive tree branches, and to create an artificial activity/bioclimatic trees. (Ref 1). Native species with lower consumption of natural resources and better adaptation capacity to be planted. More than 2,000 species have been considered until now. Sustainable agricultural practices with efficient irrigation system and use of only organic fertilizer will be one of the key features (Ref 4).

Climate-focused activities

Climate change mitigation:

  • Increase green urban nature for carbon storage (wetlands, tree cover)
  • Improve carbon sequestration through selection of more adaptable species
  • Install vertical or horizontal artificial surfaces that help with carbon storage and cooling
  • Invest in public transport/bicycle infrastructure as a means to prevent car use

Biodiversity conservation or restoration-focused activities

Biodiversity restoration:

  • Restore species (native, endangered, or unspecified)

Main beneficiaries

  • Citizens or community groups

Governance

Management set-up

Type of initiating organisation

  • Local government/municipality
  • Private sector/corporate actor/company
  • Private foundation/trust

Details on the roles of the organisations involved in the project

The project was led by the Onassis Foundation. The organization called for an open competition, the “Re-think Athens” European Architectural Competition for the creation of a new city centre, during an event that took place at the Onassis Cultural Centre. It was funded by the Onassis Foundation and was organized under the auspices and in collaboration with the Ministries of Environment, Energy & Climate Change and of Development, Infrastructure, Transport & Networks, the Attiko Metro S.A., the Region of Attica and the Municipality of Athens (Ref 5).
