Las Emparedadas

According to legend, these women were locked in cells in the walls of the churches; and it is said that in Salamanca there were walled women in the churches of Sancti Spiritus, San Esteban, Santa María, San Sebastián and San Juan de Bárbalos. However, there are those who say that they were not walled in and that they were dedicated to visiting the sick, making liturgical clothes and clothes for the offices, etc.
