The plaza de Pedro Zerolo is a public square located in the centre of Madrid, Spain.

It was created around 1836, as the plot formerly occupied by the convent of Capuchinos de la Paciencia was planted with elms and acacias.

[1] In 1931, in order to avoid the repetition of placenames, the square was renamed to "plaza de Manuel Ruiz Zorrilla", in honor of the noted republican politician.

[2] Following the end of the Civil War in 1939, the new Francoist administration toyed with the idea of renaming the square after Onésimo Redondo (a Fascist politician who had died in the war) or using the name of "Capuchinos de la Paciencia" (in a nod to the predecessor of the square), but in 1940 the authorities ruled the reset of the name to "plaza de Bilbao".

[5] The new name paid homage to the LGBT activist and former PSOE councillor Pedro Zerolo, died in June 2015 from pancreatic cancer.
