On the first four floors, a new 15,000-square-metre (160,000 sq ft) commercial area was delivered with the tower, and is linked with the La Part-Dieu shopping mall.

In his song "Lyon Presqu'île" on the album The Superb, Benjamin Biolay (born in Villefranche-sur-Saône) includes "round in pen" in his view of the main monuments of the city.
