This is one of the pair of front doors of the church at the Guadalupe Convent. With a soul of iron bars and adorned with forged iron studs, it could be 450 years old, unless replacing original doors after the numerous battles and looting Zacatecas lived through, from the Indian Wars in 1550 to the Mexican Revolution lasting until 1921. Naively I tried to move it -with one hand- looking for diverse lighting in the late afternoon. Gasping breathless of my failed attempt, could only imagine it must need four strong monks to close them at night and open in the early morning for daily mass. Since there is always a chance that a little old lady could know "the trick" to the doors, I decided not to be there beyond sunset and risk humiliation.
