Located very near the entrance to Valdepeñas de Jaén from the city, the origins of the Chapel of San Sebastián date back to the 16th-17th centuries. Its current physiognomy is the work of a later remodelling by Fray Diego Melo de Portugal in 1807.
The upper part of the plain, masonry façade is decorated with the coat of arms of the bishop, Fray Diego Melo, and a characteristic sundial. There are deep notches in the doorjambs. There are those who say that this is damage caused by passing carts, because the chapel was used as a store for compost until very recent times; but others affirm that it was because the stone was used to sharpen tools.
Inside the structure is very simple, with a Latin cross and covered with a barrel vault. The central nave is decorated with paired pilasters topped with Corinthian capitals.
Anejo is a chapel that still preserves the old cemetery that was used until the 1950s. Here lie the remains of 'Saint Luisico', a well-known healer and holy man in the region and an essential feature on the Sierra Sur Route of the Miracles.
