Castilla–La Mancha (, , ) is an autonomous community of Spain. Comprising the provinces of Albacete, Ciudad Real, Cuenca, Guadalajara and Toledo, it was created in 1982. The government headquarters are in Toledo, and its largest city is Albacete. The region largely occupies the southern half of the Iberian Peninsula's Inner Plateau, including large parts of the catchment areas of the Tagus, the Guadiana and the Júcar, while the northeastern relief comprises the Sistema Ibérico mountain massif. It is bordered by Castile and León, Madrid, Aragon, Valencia, Murcia, Andalusia, and Extremadura. It is one of the most sparsely populated of Spain's regions. Albacete, Guadalajara, Toledo, Talavera de la Reina and Ciudad Real concentrate the largest urban areas in the region. Geography Castilla–La Mancha is located in the middle of the Iberian peninsula, occupying the greater part of the Submeseta Sur, the vast plain composing the southern part of the Meseta Central. The Submeseta Sur (and the autonomous community) is separated from the Submeseta Norte (and the community of Castilla y León) by the mountain range known as the Sistema Central. Despite this, the region has no shortage of mountain landscapes: the southern slopes of the aforementioned Sistema Central in the north, the Sistema Ibérico in the northeast, and the Sierra Morena and Montes de Toledo in the south. Castilla–La Mancha is the third largest of Spain's autonomous regions, with a surface area of , representing 15.7 percent of Spain's national territory. The regional urban structure is polycentric, with no dominant central city. Insofar the largest municipality (Albacete) is located in the peripheral southeast, Madrid (outside the region), exerts influence over the extension of the so-called into the province of Guadalajara (including the provincial capital) as well as the north of the province of Toledo. The rest of urban centres lie on the central plains (with for example, the presence of intermediate agro-cities in La Mancha), contrasting with the sparsedly populated mountains and other peripheral areas. Relief The Meseta is the dominant landscape unit of a great part of the territory of Castilla–La Mancha: a vast, uniform plain with little relief. The west-to-east Montes de Toledo range cuts across the meseta separating the (northern) Tagus and the (southern) Guadiana drainage basins. The most outstanding peaks of this modest mountain range include La Villuerca () and Rocigalgo (). In contrast, a more mountainous zone surrounds the Meseta and serves as the region's
