We were both delighted and honoured to welcome and showcase PYRAMIDION for the celebration of the inaugural International Day of Light at UNESCO headquarters in Paris on 16 May 2018.
PYRAMIDION is a wonderful example of the work of Milène Guermont, combining art and science and technology to reinforce the message of the unifying power of light as a symbol while also highlighting innovative and creative uses of advanced engineering technologies.

A new pyramid is born in London & Paris


Who has not dreamed of discovering a pyramid? Who has ever dreamed of moving a pyramid? Who has ever thought of illuminating a pyramid located thousands of kilometers away to the rhythm of her/his own heartbeat?

PYRAMIDION is the continuity and the complement of the monumental "art-architecture" PHARES; both travel. The "trip of the pyramid" benefits from the patronage of the French National Commission for UNESCO and the label "2018, European Year of Cultural Heritage."

PYRAMIDION is an interactive sculpture of golden metal & light measuring 3.7 m in height. It is born in Paris on February 9, 2018, into the architecture by Renzo Piano of the Foundation Jérôme Seydoux - Pathé. Then, it stops by in front of the facade signed by Auguste Rodin before being installed in the Egyptian blue heart of the Town Hall of the 13th arr. until May 14, 2018. On March 8, PYRAMIDION lights up at the rhythm of the heartbeat of each "visitor/actress" who touches its cardiac sensor.

On May 16, 2018, PYRAMIDION is installed next to the WALKING MAN by Giacometti at the UNESCO headquarters; this work was chosen to celebrate the first International Day Of Light. On May 19, the mini pyramid pulsates at the rhythm of the public's heartbeat of UNESCO for the European Night of Museums.

On www.youlightme.com you can see PYRAMIDION, at a distance, illuminate at your own rhythm. You can personalize the short video that comes with it and share it by sms, email or social networks.

As the Obelisks are designed in pairs, a twin work, PYRAMIDION TWIN, is born on June 23, 2018, in London in front of the Trinity House in the framework of The London Festival of Architecture and to celebrate The International Day of Women in Engineering. Each evening of this summer, PYRAMIDION TWIN lights up automatically except on June 23, 29 and September 14 and 22 (for the London Open House Day): you can illuminate this luminous pyramid to your own heartbeat by putting your finger into its connected cardiac sensor.

For the birth of PYRAMIDION TWIN in London, the British soprano Katerina Mina sings into it a capella. Her finger is into its cardiac sensor, so the luminous sculpture lights up live to the rhythm of her heart (movie of the performance here).

On June 27, the second PHARES party occurs with PYRAMIDION on a boat floating on the Seine River in front of Musée d'Orsay. This mini pyramid sunbathes and looks at the pyramidion of the Obelisk of Place de la Concorde until the end of the year here.

For the Europe Heritage Days, on September 14, a long-distance interaction between the two PYRAMIDIONS happens: touch the pyramid in London and the one of Paris lights up at your own hearbeat simultaneously.

During NUIT BLANCHE, on October 6, the public can illuminate PYRAMIDION which is floating on the Seine River.

In October 2018, the mini pyramids move in their cities: PYRAMIDION pulsates during several days at Lieu Secret-Paris and PYRAMIDION TWIN at ICE-Westminster.

In December 2019, after having floated during one year and a half on the Seine River next to Musée d'Orsay, PYRAMIDION goes to Normandy to rest surrounded by soft countryside.

Supported by UNESCO, other tiny pyramids will be installed around the world and communicate with each other thanks to the "sky" in 2021. To welcome a PYRAMIDION to your country, email: This email address is being protected from spambots. You need JavaScript enabled to view it.
