to bring their corn to the mills to be ground. In 1836 a chapel in the parish of Defynnog, Brecknockshire, was dedicated to Saint Callwen. Capel Colwyn or St Colwen's in Callwen, Glyntawe, was a chapel of ease to Defynnog until around 1868, when Glyntawe became a separate parish. The Imperial Gazetteer of England and Wales (1870–72) described Glyntawe as "a hamlet-chapelry in Devynnock parish, Breconshire; 7½ miles W of Brecon town and r. station. Post town, Brecon. Pop., 99. Houses, 20. The living is a p. curacy in the diocese of St. David's. Value, £80. Patron, the Vicar of Devynnock." On 1 July 1893 a new Church of Saint Callewn was substituted for the older building in the parish of Glyntawe by Basil Jones, bishop of St David's. Historical census figures for the hamlet of Glyntawe are: 1841 - 118 people 1851 - 107 1861 - 99 1871 - 102 1881 - 133 1891 - 144 1901 - 147 The community was never industrialized. The people of Glyntawe would have farmed, worked in the quarries or in Penwyllt brickworks, or perhaps worked at Craig-y-Nos Castle. The church was rededicated to St John the Baptist in 1964–65, although it is still called Callwen Church by the locals. The school in Callwen was closed in 1970. Today The rural community of Glyntawe, which includes the hamlet of Callwen, is part of the Community of Trecastle. The school is now the Glyntawe Outdoor Centre, an activity centre run by Dulwich College. Also called the Dulwich College Field Centre, this is a hostel that can sleep up to 40 people, and makes a base for outdoor activities such as hiking, mountain biking, caving or fishing. Glyntawe contains the National Showcaves of Wales at Dan yr Ogof, a major tourist attraction. This is part of a large system of caves which includes the Ogof yr Esgyrn. Craig-y-Nos Castle is very close to Glyntawe. Notes Sources Populated places in Powys
