Caerwys (Care Wiss) A few miles west of Holywell, the tiny settlement of Caerwys (Care Wiss) proudly proclaims itself as the smallest town in Britain, for it was restored to town status with its own mayor in 1974 after the period since 1886 as a mere Parish. Caerwys was granted its first borough status as early as 1290 by Edward I, having earlier received a charter from Henry III. The town also boasts of containing the oldest lived-in house in Wales, with parts of a 1480 dwelling remaining in an 1800 alteration. Cuz Connie
