This hermitage is located on the road to Zegama. It is built with magnificent ashlar masonry under a wooden roof. Its purpose was to serve pilgrims. It dates to 1589, and it was renovated in the 19th century. It has a rectangular tower on the roof with a bell in the middle. The date 1722 appears on a wall.
There are three altars inside. The central one is decorated with a well-conserved baroque reredos. There are carvings of Ignacio de Loyola, Francisco de Javier and Carlos de Borromeo on it. Angels of black paint can be seen on the peak. The image of San Sebastián is in the centre. The small San Roque from the 18th century is next to it. There is another image of San Sebastián on the right, which is older than the one on the altar.
The feast day of this hermitage is celebrated on 20 January (or the following Sunday). The people who live in the house next door do the job of sacristan, and they make a meal for the local residents.
