She was one of the women who suffered repression and torture under the Franco regime for her being a member of the anarchist trade union federation CNT and the Anti-Fascist Youth Union (UJA). She arrived in Santa Coloma de Gramenet with her family in 1921. At just 14 years old, she started working as a weaver at Pañolerias Baró, in the current district of Hora-Guinardó. While there, she came into contact with the CNT, of which she was a member from 1934 onwards. Her activism made her one of one of the union’s leading figures, and in 1936 she was appointed general secretary and treasurer. Barcelona’s occupation by the Francoist army marked the beginning of a wave of arrests, of which Romera was a victim. She was tortured for three days and sentenced to life imprisonment. She died prematurely in the Les Corts Women's Prison, as a result of tuberculosis aggravated by the effects of torture and the unhealthy living conditions that so many women suffered unjustly during the Franco regime.
Appointed the secretary general and treasurer of the CNT in 1936, in 1939, she was tortured for three days and condemned to life in prison at the Les Corts Women’s Prison, where she died.
