Tyddyndu farm is located approximately two and a half miles north west of Cribyn. According to heritage consultancy Trysor, 'Tyddynddu is shown on the Ordnance Survey's Original Surveyors Drawings map of 1811. The farmstead also appears on the Ordnance Survey's First Series map of 1834, the name by now spelled Tyddyndu.'
'The early Ordnance Survey maps do not show any detail of the farmstead's field layout. The Llanarth parish tithe map of 1840 provides the first detailed map of the area. It records that David Lewis was the owner and occupier of Tyddyndu, measured at just over 223 acres. It maps the farmstead in detail, and the accompanying tithe schedule lists the field names. The field names, as recorded in the tithe schedule, were: House & Garden etc; Cae Rhos; Rhos Twarch; Cottage & Garden; Cae Sycamore; Bank Ucha; Cae Bach; Cae oddiar ffordd; Cae Symbol; Cae pant Fanog; Cae Gwair; Wayn Ganol; Cae Roft; Cae Gwair pella; Cae Garw; Cae Quarry; Cae yr ydlan; Cae Tyhwnt; Cae Rhyngon...(indecipherable); Cae Newydd; Cae Fron; Cae y Moyddyn; Cae Gwastad; Cae Post; Cae delin; Close; Wayn Arw; Cae Mawr; Wayn Ucha; Cae gwair issa; Cae ye odyn.'
'The 1889 1:2500 scale Ordnance Survey map provides the first clear depiction of the layout of the farmyard and its buildings. This shows the farmhouse in its present position, with outbuildings arranged around a farmyard to the north of the house. This historic core to the farmstead is still identifiable today. The 1905 1:2500 Ordnance Survey map shows the same layout of buildings.'
'During the second half of the 20th century, the farm building complex began to expand. The 1975 1:2500 Ordnance Survey map shows a group of larger, modern sheds had appeared to the northwest of the farmyard. This expansion continued into the early 21st century, by when a substantial group of modern agricultural buildings associated with the dairy complex had appeared to the northwest, covering an area of approximately 100m by 60m.'
