On 24 September 2022, in the presence of the authorities of the City and State of Fribourg, the Esplanade Armand-Niquille was inaugurated. The many people present at this event discovered the bronze commemorative plaque that the foundation commissioned from the artist Marc Monteleone, an admirer and great connoisseur of Niquille's work. It shows a portrait of Armand Niquille, inspired by one of his self-portraits painted in 1954, and a quotation from the artist, taken from his book "Le veilleur de solitude". A nameplate donated by the City of Fribourg also marks the location of the Esplanade Armand-Niquille, on the low wall overlooking the Bourg, at the top of the Escaliers du Collège and next to the courtyard of the Collège Saint-Michel.
