Situated in the midst of "Quijote's Road" (Ruta del Quijote), Belmonte is not only known as the birthplace of the poet Fray Luis de León, but also for its impressive 15th-century fortress. Its old town has been declared Property of Cultural Interest.

An overview offers up a uniquely beautiful town with noble buildings and major monumental heritage. The unquestionable star is the Castle, which sheltered Doña Juana la Beltraneja, and where a great number of movies have been shot.  Located on a hillside, the exterior pentagonal complex has a Gothic gate and is linked to the city walls running down to the town. Highlights in the triangular interior are the Mudéjar coffered ceilings, the plasterwork and the Gothic reliefs. Other building of interest is the palace-alcázar of Don Juan Manuel. The 15th-century city walls have five access gateways, three of which still stand: San Juan, Chinchilla and Puerta Nueva. The Gothic church of San Bartolomé is also a highlight, the construction of which was led by some of the greatest artisans of the period. Its choir stalls belonged to the Cuenca Cathedral, and the church keeps the font of Friar Luis de León. In addition, the old Jesuit Monastery is, amongst others, well worth a visit: a Baroque construction from the 17th century, its cloister is part of Plaza Muñoz Grandes, whilst the rest of the building currently houses the Courts and the Post Office building.
