Boulevard Henri IV is modern (1866), cut across the site of two old convents. Rue Castex leads out of it where stood once the convent des Filles de Ste-Marie; its chapel, now a Protestant church, is entered at No. 5. The Caserne des Célestins was built in 1892 on the site of part of the large and celebrated convent of the Célestins, an Order founded in 1244 by the priest who became Pope Celestin V. The Carmelites who at first were established here, greatly disturbed by inundations from the Seine who overflowed her banks in those long-past ages, even as she does to-day, quitted their quarters on this site. The Célestins who came to Paris in 1352 and took over these abandoned dwellings were protected and enriched by Charles V, inhabiting the Palais St-Pol close by. The Order was suppressed in 1778, before the Revolution suppressed all Orders--for the time; and in 1785 the convent here was taken for the first deaf and dumb institution organized by abbé de l’Épée. The convent chapel with its numerous royal tombs, the bodies of some royal personages, the hearts of others, was razed in 1849. Some vestiges of the convent walls remained standing till 1904. Where the boulevard meets the Quai des Célestins, we see now a circular group of worn, ivy-grown stones; an inscription tells us these old stones once formed part of the Tour de la Liberté of the demolished Bastille. They were unearthed in making the Paris Metropolitan Railway a few years ago. The birds make the remnant of that old tower of liberty their own to-day and passers-by stop regularly to feed them.
