The Scene of the Events: "Los Lunarejos" farm, a rustic property devoted to cereal crops, owned by lieutenant general Gabriel Tassara Buiza, located some two kilometers from the locality of Aznalcollar, some 40 kilometers from the city of Seville. It is a vast expanse of agricultural land of the highest quality, with many artesian wells and crossed by the Pilar Viejo stream. The subsoil lacks minerals despite the proximity of the rich veins of Aznalcollar (the world's largest deposit of pyrite), according to Juan Manuel Turmo, an engineer with Andaluza de Piritas, S.A., a company that works the nearby Banco Central fields. At the time, this property was cultivated with melons in a sharehold with the Pérez Miranda brothers, known by their nickname "Los Chícharos" (the Peas), well known in Aznalcollar for their seriousness and moral character.
