Eastern State Penitentiary , Philadelphia, Pa.

ESP is a national historic landmark, built in the 1820s, it was the first penitentiary. It was designed so that each inmate had his own cell. Each cell had a single small window in the wall and ceiling situated such that "God's rays would shine upon the prisoner and help him repent." Most of the prison is now in disrepair.

I noticed this stool highlighted, as described, with "God's rays" and could indeed feel the solitude and reflection.
