How can the landscape and architectural environment of the Observatory be preserved?

The preservation of the landscape and architectural heritage is a major objective of the T7 tram extension project.

The choice to build the Observatoire underground station, as well as part of the tunnel route, makes it possible to limit the impact of the infrastructure on the surface and to preserve the views of the Camille Flammarion Observatory and the Parc de la Mairie.

The future forecourt of the Observatory station will be the subject of quality landscaping, designed in conjunction with the Architect of the Buildings of France. Public spaces will be redeveloped to facilitate pedestrian movement, reinforce the place of vegetation and improve user comfort, in particular through coatings that limit heat island effects.

The project also provides for the enhancement of two major heritage elements in the area: the Camille Flammarion Observatory, classified as a Historic Monument, and the Ducastel building, thanks to the development of a new tree-lined forecourt that will contribute to enhancing their architectural and landscape environment.
