[2] The director of the works was Mariano Benlliure,[3] who counted with help from Miquel Blay, Francisco Asorey and Juan Cristóbal [es] for the sculptural elements.

[5] The original project included a bronze sculpture of Cuban president Gerardo Machado,[3] yet, following the delay in the inauguration of the monument, it was never added to the ensemble.

[5] The leading element on top of the monument is a female allegory of Cuba, wearing a thinly draped tunic and a Phrygian cap, designed by Blay.

[6] The pedestal displays the supporting figures of Christopher Columbus (by Asorey), Isabella I of Castile (by Juan Cristóbal),[2] as well as the coat of arms of Cuba.

The ceremony was attended by José Finat y Escrivá de Romaní (Mayor of Madrid), Alberto Martín Artajo (Minister of Foreign Affairs), Mariano Vidal Tolosana (responsible for American affairs within the Foreign Ministry), the ambassadors of Cuba in Spain (Antonio Iraizoz) and Spain in Cuba (Juan Pablo de Lojendio [es]), and Mariano Ossorio Arévalo [es] (President of the Provincial Deputation of Madrid), among others.
