On the general calendar, today is the feast of St Monica, but in England, it is the feast of the Carthusian Martyrs of London, the first three of whom were put to death on this day in the year 1535, the earliest victims of King Henry VIII’s greed and impiety. By whatever strange intuition, the YouTube algorithm (which normally has so many bizarrely unhelpful suggestions to offer) managed to dig up this brief video about the only Carthusian monastery in the United States, the Charterhouse of the Transfiguration on Mt Equinox in Sandgate, Vermont. As you can see, the building is made out of the material which was most readily available in the area at the time of its construction, granite, which perfectly suits the deep austerity characteristic of Carthusian life.
