Prehistory There is evidence of human occupation of this site from Neolithic times. Excavations in the 1960s at the site of the current Industrial Estate uncovered two large henge monuments and a series of hengiform pit circles from the late Neolithic period. Excavations in 2006 and 2007 at the Bryn Cegin site (extending the industrial estate) found an early Neolithic house and later, possibly Romano-British, settlement History In 1648 during the English Civil War the Battle of Y Dalar Hir was fought near Llandygái. Royalist forces of 150 horse and 120 foot soldiers led by Sir John Owen engaged Parliamentarian forces led by Colonel Carter and Colonel George Twistleton. The village of Llandygái is recorded at the beginning of the nineteenth century as consisting of eight or nine houses. The village was later developed by quarry owner The 1st Baron Penrhyn (1800-1886) as a ‘model village’ for his estate workers, in which ‘no corrupting alehouse’ was permitted. It lies immediately outside of the walls of the Penrhyn Castle demesne walls, with the entrance to the village being some from the castle's Grand Lodge. Lord Penrhyn, a Scottish aristocrat, had inherited the Penrhyn Estate from his father-in-law, George Hay Dawkins-Pennant (1764-1840), in 1840. This model village was mostly constructed in the 1840s in a ‘vernacular revival’ style which conformed to the Picturesque ideal. The model village was built within the loop of the road to Conwy from where it branched off Telford’s newly built Holyhead to London road. Each house was built in a similar style but none was to be identical. They were furnished with ample gardens and the layout was such that no house’s front door faced another. Llandygái Church A church was founded by Saint Tegai (or Tygái or simply Cai) in the fifth century. Relics of the Saint, including a stone coffin and a cross bearing his name, are kept at the church. The present church dates to around 1330 and was much restored and extended by the diocesan architect, Henry Kennedy, in 1853. The church is
