What might a sixteenth-century Spanish nun and an eighteenth-century French architect have in common? Saint Teresa of Avila and Charles-Axel Guillaumot both left behind a mostly invisible legacy. Hers was a vision of the interior castle of the spirit within us. His was to save Paris from collapsing back into the quarries beneath it by building a support city below ground. Today, we can read of the realm The Nun built with her words, and we can visit a fraction of the realm The Architect built beneath Paris. Hope of Stones invites you into a cross-century conversation among The Nun, The Architect, and The Poet that explores the desire to create and connect across time and other unseen things.
