The smaller Ivanovsky priory is dedicated to St. John the Precursor, the patron saint of Ivan the Terrible. The oldest church of the priory was commissioned by Ivan's father, for the benefit of the "mendicant brethren," soon after his visit to the monastery in 1528. Subsequently, the monks incurred the tsar's displeasure by constructing St. Vladimir's Chapel over the grave of the exiled Prince Vorotynsky. Although the tsar chastised them for having broken canonical requirements, the chapel — which became the first family mausoleum in Russia — survived Ivan's reign and was expanded to its present form in 1623.
