The washhouse was operated in the 18th and 19th centuries; it is an interesting trade in which the wool was washed by the animals of the migratory herds with water from the pond Barruecos de Abajo of Extremadura.

[10][11] The opening collection Wolf and Mercedes Vostell offers an extensive and varied tour through the selection of cycles by the founding artist.

[12] It consists of five works, which make up the special reference of this museum: Automobile-Fever (Auto-Fieber) (1973),[13] Fluxus-Buick-Piano (1988)[14], Endogene Depression (1975–1978), Requiem for the forgotten (Réquiem por los olvidados) (1986), The Breakfast of Leonardo da Vinci in Berlin (Das Frühstück von Leonardo da Vinci in Berlin) (1998)[15] As objects, most of these parts contain elements of the fetishistic symbolism of the 20th century.

Also worth mentioning are the works Transmigration III (1958–1959), in which a television set is integrated, and Foreign mountain (Montaña extranjera) (1958), with which Wolf Vostell began his production in Extremadura.

Di Maggio established a personal relationship with the Fluxus artists, took care of their works and exhibited them first in the multipurpose room Multhipla and later in the Mudima Foundation.

The donation consists of a series of works, most of which are Fluxus actions and interventions, so that the Photographs, videos, manifestos and various texts are the necessary additions to these bundles of files.

The exhibition comprises 250 works, installations, Paintings and Sculptures by 31 artists of European, North American and Asian origin who, since the late 1950s and 1960s, have synthesized the upheavals in all areas of culture in the Happening and Fluxus movements in favour of a renewal of the artistic field in an interdisciplinary and intermediary manner, transcending everyday life and as the seed of a fundamental social transformation.
