The baptismal font in the Parish of San Andrés is a beautiful Romanesque example of this liturgical element. It is probably from the 13th century, made of granite stone, of large dimensions since it was designed for baptism by immersion, and it has the peculiarity of having a wooden lid that, although it is not the original (since it dates back to the XVI century), constitutes the only testimony of this ancient element in the city, and one of the few in Castilla y León.
 

On the rear wall of the baptistery there is a painting that constitutes an interesting testimony of Segovian Holy Week during the Baroque period. It represents the titular images of the Slavery of Our Lady of Solitude and the Holy Sepulcher of Christ, which had its headquarters in the Hospital of San Juan de Dios, located on Calle Desamparados. These images went out in procession through the streets of Segovia during the night of Good Friday. The origin of this painting is unknown, since it could have belonged both to the disappeared Convent of La Merced and to the aforementioned Hospital of San Juan de Dios. Two baroque canvases complete the decoration of this chapel. The first of them represents the Conduction of the Body of Christ to the Sepulchre. The second is an adoration of the Blessed Sacrament by the angels that must have belonged to the now defunct sacramental brotherhood of San Andrés. A few meters from the baptistery, we find the already mentioned altarpiece of Santa María de Cervellón (from the disappeared convent of La Merced, which is inserted in an old funerary arcosolium.
