Guadalajara, chief town of its province, situated above the left bank of the Río Henares some 56km/35mi from Madrid, is now very much under the influence of the capital. Its name is derived from the Arabic Wad al-Hajarah ("river of stones"). The powerful Mendoza family, who gained possession of Guadalajara in the 14th century, left their mark on the town. During the Spanish Civil War, in March 1937, the "battle of Guadalajara" between Republican and Italian forces was fought at Brihuega, northeast of the town.
From Torija, C 201 runs east to the old fortified town of Brihuega (alt. 886m/2907ft), situated above the valley of the Río Tajuña. Above Brihuega can be seen the ruins of the 12th century Castillo de Piedra Bermeja, and in the town itself are the parish church of Santa María de la Peña, with a fine retablo, the arcaded Plaza Mayor and the gardens round the Real Fábrica de Paños (the old Royal Cloth Manufactory).
From Brihuega the road (C 201, then N 204) continues to Cifuentes, at the foot of the Sierra de Megorrón. The town, which takes its name from the numerous springs in the area, has a handsome Plaza Mayor and a church (12th-13th century) with a Late Romanesque doorway. On a hill above the town is a castle built by Juan Manuel in 1324.
The Convento de la Piedad, a nunnery founded by Doña Brianda de Mendoza about 1530, is now an institute. The finest part of the building is the cloister, which has Plateresque doorways and double arcades. The foundress is buried in an alabaster tomb.
From the turn-off for Sigüenza N II climbs through Algora (alt. 1,116m/3,662ft) into the Sierra Ministra, from which there is a fine view of Sigüenza. It then continues by way of Saúca (alt. 1,200m/3,940ft) to Alcolea del Pinar (alt. 1,205m/3,955ft), where it turns north to Medinaceli.

At Alcolea del Pinar we turn right into N 211, which climbs to the Puerto de Maranchón (1,250m/4,100ft) and then descends to Molina de Aragón, a picturesque little town with a history going back to pre-Arab times. On a hill above the town is an imposing stronghold surrounded by walls and towers, the finest of which is the Torre de Aragón (11th C.). Features of interest in the town are the old Jewish quarter and the 12th Century church of San Gil, which contains the tomb of Doña Blanca, Duchess of Molina (d. 1283).

The 13th century church of Santa María de la Fuente, built on the site of an earlier mosque, has a minaret-like tower in Mudéjar style and contains a number of 15th century tombs.
South of Cifuentes on N 204 is the Mar de Castilla, a very beautiful lake district, with two large artificial lakes, the Embalse de Entrepeñas and Embalse de Buendía, and a smaller one, the Embalse de Bolarque. The water stored in these reservoirs is used for irrigation and for the production of hydro- electricity. At the Embalse de Zorita, to the south of the lake district, there is also an atomic power station. These great expanses of water and the country round them are a popular recreation area for the people of Madrid.
Leave Guadalajara on N II, which runs northeast over the Castilian plateau in the direction of Zaragoza, coming in 18km/11mi to Torija (alt. 964m/3,163ft), with a 13th century Templar castle which was destroyed by Juan Martín el Empecinado in 1811 but has been restored in recent years. The parish church contains some fine pieces of goldsmith's work.
The village of Villaviciosa, a short distance away from Brihuega, was the scene of a battle in 1710 which decided the result of the War of the Spanish Succession and brought Philip V to the throne.
