In 1939, the MEG moved into the disused buildings of the Mail primary school in boulevard Carl Vogt.

It was designed by Graber Pulver Architekten AG, with ACAU architecture and town planning, in partnership with the civil engineering firm Weber + Brönnimann EG.

The galleries and an auditorium are located in the basement; the cafeteria, museum shop and ticket office are on the ground floor, facing the garden.

Upstairs are restoration and cultural outreach workshops, as well as the library, which is named after a generous patron, Marie Madeleine Lancoux.

The three buildings in the ensemble - the old museum, the new MEG and a primary school – enclose a small square planted with trees and flowers.
