In the presbitery there is a wooden golden bandstand, placed over a stone altar, which is the most significant thing in the chapel. Its construction was supported by Francisco de Otero y Cossío, born in the village of Turieno (Camaleño), archbishop of Santa Fé de Bogotá. Inside the bandstand, the "Lignum Crucis" is kept and venerated. The relic was brought from Jerusalén to Astorga by Santo Toribio, guardian to the Saint Places, facing the threat of the Persian´s invasion; there, in its natal town it stayed until, most probably, due to the Arabs´ invasion in 711, it was transferred to the monastery in Liébana together with the dead body of Santo Toribio and other relics which the saint brought from Jerusalén.The first written evidence of the relic´s presence in the monastery of Liébana is through an inventory made in 1316. In the XVI century the Benedictine monks divided the Saint Beam in two, arranging it in the shape of a cross and inserting glossed a silver reliquary. Nowadays the pilgrims can kiss the relic througt an opening in the reliquary, which leaves out a wooden piece. In1938 an official measurement was carried out giving the following resulting dimensions: 63 cm in its vertical piece, 39 cm in the horizontal one and a width oscillating between 4 and 9 cm, meaning this is the biggest remaining fragment of the cross where Christ died.
