It has been proposed that Lorca was actually killed at Fuente Grande which is on the road between Víznar and Alfacar. For the context see Ian Gibson, 1983, The Assassination of Federico García Lorca, (Penguin Books) More recently it has been proposed that the execution site was on open countryside near the farm of Cortijo de Gazpacho.
