Lemme is a contemporary art exhibition space and sculpture by artist Pierre Vadi. Lemme is located in the park of the Arsenaux cultural center, which houses the Médiathèque Valais-Sion. Pierre Vadi designed this space as part of a public art project for Les Arsenaux. From 2019 to 2021, he curated twelve exhibitions in this miniature architecture. Since 2022, the curatorship of exhibitions has been put out to tender every two years. The aim is to encourage the next generation of curators in Valais. In 2024, Christophe Constantin took over as curator.
Lemme is located in the public space and is freely accessible at all times.
