Through a late 18th-century Rococo chancel screen adorned with a tiara and the papal keys, you’ll enter the museum’s halls, constructed in the late 16th century under the direction of Juan Bravo.

The first of these halls, known as the former vestry of the canons, features a groin vaulted ceiling supported by Renaissance corbels. This room is divided into two levels. On the lower level, you’ll find a series of display cases containing documents, choir books, mitres, rings, pectoral crosses, reliquary boxes, and a crucifix with a Rococo base. Dominating the room’s centre is a sizeable display case containing a life-size graphic representation of the Holy Cloth from the Last Supper, a precious relic safeguarded within these Cathedral walls.
Ascending to the upper level, the focal point is a Virgin Mary crowned by angels, a masterpiece crafted by Lucas Mitata in 1595 that once was at the centre of the grand old high altar. Among the display cases, you’ll notice two simple monstrances with a relic of the Holy Thorn from the early 17th century and an altar cross with a relic of the Lignum crucis from the late 16th century.

Chapter House

Enter now the second chamber that once was the Chapter House, covered by a dome supported by pendentives. Here, you’ll admire a collection of sacred vessels (chalices and ciboria) alongside monstrances, mass cruets, graphic documents, and a set of liturgical vestments known as the Toledan Set, as it was made by Alonso de Medrano in this very city in 1725, using gold cloth.

The chamber centre stage is occupied by the Cathedral’s most revered relic— the Cloth traditionally associated with the Last Supper and the institution of the Eucharist. It rests within a Baroque silver reliquary box, meticulously crafted in 1678, and generously bestowed upon the Cathedral by Bishop Fray Francisco Sarmiento de Luna.

Lastly, we venture into the third chamber, known as the treasure room, where you will find copies of plans and blueprints from the various phases of construction of both the cathedral and the tower. In the only glass case, you’ll find a set of liturgical vestments known as the Pelican Set. Crafted in Valencian workshops in 1870, it was a gift from Friar Pedro Núñez Pernia, whose coat of arms adorns the chasuble.
