34 Chapel of St. John the Evangelist

The sepulchre of Sancho Sanchiz de Oteiza, the founder of the current chapel, is a masterpiece by Jehan Lome (author of the Royal Mausoleum), created between 1420 and 1425.

To the left is the altarpiece of St. John Evangelist, a Gothic structure with paintings close to the Renaissance style.
