Castile (; ) is a territory of imprecise limits located in Spain. Its extension is often ascribed to the sum of the regions of Old Castile and New Castile, as they were formally defined in the 1833 territorial division of Spain. Those two regions cover the following modern autonomous communities: the eastern part of Castile and León, Castile-La Mancha, and Community of Madrid as well as Cantabria and La Rioja. However, it has been pointed out that in practice the modern limits of "Castile" are imprecise, and that this name has been used mainly as a reference for the image of Spain as a nation.
