«This chapel and nave made parishioners and a priest. Year 1714». The inscription printed on a slab dates the church of San Martín, located in the heart of Taramundi; a religious temple that, due to its large dimensions, can be seen from any point in the town or from the mountains. A church, which three hundred years later the descendants of those parishioners from the 18th century, keep standing by financing its rehabilitation. Its high, square and solid tower stands out, topped by a slate capital, although it is not the original one that was destroyed by lightning. The current one dates from 1952. Inside there are six altarpieces, all of them in Neoclassical style, except for the main altarpiece in Baroque style.
