The dome of the building (the tallest in Madrid at the time of its opening in 1911, erected as premises of La Unión y el Fénix Español) was originally topped by a sculptural group by René de Saint-Marceaux depicting Ganymede and a Phoenix bird.

[1] Following the purchase in 1972 of the building by a company named Metropólis and the declared intention of La Unión y el Fénix Español to take the original sculptural group elsewhere, a project for a new sculpture was entrusted to Federico Coullaut-Valera.

[2] The original sculptural group was moved to Castellana 33, next to the new La Unión y el Fénix Español headquarters,[3] also spawning some replicas.

[4] The original plaster cast of the winged victory was auctioned for 2,200 euros in June 2019.

[5] The use of a fully dressed "Catholic angel-like" reimagination of the statue (rather than the real naked figure of Nike) as part of a Christmas card published by the Ayuntamiento de Madrid generated online controversy in December 2020.
