One of the most notable aspects of Yunclillos' heritage is its religious architecture. The parish church of Saint John the Baptist is the town's main religious building. This church, built in the 16th century, features a transitional style between Gothic and Renaissance. Its façade is sober, but its interior houses valuable works of art:
Mural Paintings: Inside the church, you can find some mural paintings dating from bygone eras, depicting scenes from the life of Saint John the Baptist.
Main Altarpiece: The main altarpiece is a masterpiece of Toledo Baroque, crafted in gilded wood and depicting various scenes from the saint's life.
Image of Saint John the Baptist: The image of the saint that presides over the altar is greatly revered by the locals, and a festival is held in his honor every year.
The church is not only a place of worship but also acts as a cultural center, hosting various events throughout the year, including concerts and art exhibitions. The frescoes and interior ornamentation bear witness to the town's religious and cultural past.
