Born to a poor family, the son of a baker, Querol was educated under Ramon Cerveto Bestraten (1829–1906).

At the age of 18, he left his job at his father’s bakery and moved to Barcelona, where he worked as an apprentice at the studios of Domingo Talarn and of the Vallmitjana Brothers.

He also attended sculpture classes at the Escola Provincial de Belles Arts (called colloquially “la Llotja”).

Querol also worked as a businessman, dealing in Carrara marble; was involved in art expositions; wrote literary pieces under the pseudonym El Plutarco del Pueblo, the "People's Plutarch"; served as vice-director of the Museo de Arte Moderno de Madrid (1892–1895) and a Conservative deputy to the Cortes (for Roquetes); and was a man about town.

The elaborate sculpture, representing a statue of Liberty on a tower, with an extensive frieze at the base, all of it set in a pool with fountains, surrounded by monumental bronze figures dedicated to the Constitution of Argentina and the country's regions, was designed before Querol's death.
