The Tour Prisma, 97 meters, 27 floors, 27,488 m², was designed by Jean Willerval in 1998 and renovated by Axel Schoenert in 2011, and is located in the heart of the La Défense district.
Actif Signal creates the facade sign and VIP entrance cladding.
The sign spans more than 12 meters, with letters 2.70 meters high. It is illuminated by almost 500 LED modules.
Actif Signal had already acquired the Gan Eurocourtage brand, which occupied the Tower until 2010.
The VIP entrance cladding, also designed by Actif Signal, features a full-height (8-meter), seamless light net.
Tour Prisma has been home to the headquarters of business law firm Fidal since 2014.
Founded in 1922, Fidal is the leading business law firm in France and the second largest in continental Europe in terms of size and sales, with some 1,300 lawyers and legal experts in France and partners in 150 countries.
