Castillo de la Serrezuela, located in Dos Hermanas near Seville, dates to medieval times, with its earliest documented reference appearing in the will of Pedro Rodríguez de Esquivel in 1414. By the late eighteenth century it had evolved into an olive estate, representing the transformation of a strategic fortress into agricultural property. Today, substantial remains survive including a thick wall constructed from brick and rammed earth, measuring 1.80 meters in depth and bearing fragments of Roman and medieval ceramics. The structure is classified as a Bien de Interés Cultural, marking its importance to Andalusian heritage. The ruins stand as testimony to the region's complex medieval history, when fortified settlements defended these valuable Sevillian lands.
