Tyburn Convent (London, England)

Situated near the site of the infamous Tyburn Tree, the King’s gallows between 1196-1786, Tyburn Convent is dedicated to the memory of 105 Catholic martyrs who were executed here between 1535 and 1681. The actual Tree is no longer in existence, of course, but the convent is worth a quick stop to visit the crypt beneath the monastic church called Shrine of the Martyrs which has relics and mementoes of the martyrs, as well as a replica of the Tyburn Tree. Among the mementoes reportedly on display are bloodstained pieces of clothing, locks of hair, bone fragments, and even lengths of rope from the nooses! Twisted sisters, indeed!
