Near the iconostasis, at the southern wall, are found the relics of the monastery’s founder, St. Sergius. Until the end of the sixteenth century they were in a wooden reliquary; then they were moved into a silver tomb, created by order of Ivan the Terrible. The reliquary is decorated with ornate embossed stamps with texts from the Life of St. Sergius. A silver canopy weighing twenty-five pounds was added by order of Empress Anna Ioannovna, and the engraved cover of the reliquary dates from the nineteenth century.
