The National Museum of Esperanto de Gray was founded in 1977 by Georges Junier, known as Géo Junier. Its official inauguration took place in 1987 in the presence of the Polish consul, one hundred years after the creation of Esperanto by Zamenhof. The museum occupies one floor of the Maison Pour Tous and exhibits collections of various objects related to Esperanto. In the square adjoining the museum, Géo Junier has installed an analemmatic dial echoing Zamenhof's project to unite people through Esperanto.
