From the Royal Commission on the Ancient & Historical monuments of Wales, Website;
"St Llawddog's church was a parish church during the medieval period, belonging to the Deanery of Emlyn and appropriated to St Davids Cathedral. In 1833 the living was still in the patronage of the Bishop of St David's. In 1998 St Llawddog's was a parish church belonging to the Rural Deanery of Emlyn. It is situated within a curvilinear churchyard, immediately north-east of the A484 and some 100m north-east of Parc-y-domen motte (NPRN 304127), a Scheduled Ancient Monument. A Latin inscribed stone is located near the western churchyard boundary, adjacent to the south-west corner of the church building. It is noted to have originally been located in a nearby field and was reportedly moved to its current location in 1894. St Llawddog's well (NPRN 418381) is situated some 140m west-north-west of the church.
The medieval church may have been sited immediately south of the present building. In 1844 it was described as some 50ft long and 25ft broad, with 230 sittings. In 1855 it was described as being comprised of nave, chancel and Tran-septal south chapel. The chancel arch was described as pointed, with a projection in its south wall. There was also a pointed west door and a western double bell-cote.
The current church is a Grade II listed building, constructed of local slate rubble. It was built in 1872, to the designs of Middleton and Goodman, Cheltenham, and has not been substantially altered." Text Source: (

"Ordnance Survey Bench marks (BMs) are survey marks made by Ordnance Survey to record height above Ordnance Datum. If the exact height of one BM is known then the exact height of the next can be found by measuring the difference in heights, through a process of spirit levelling.
Most commonly, the BMs are found on buildings or other semi-permanent features. Although the main network is no longer being updated, the record is still in existence and the markers will remain until they are eventually destroyed by redevelopment or erosion.
Bench marks are the visible manifestation of Ordnance Datum Newlyn (ODN), which is the national height system for mainland Great Britain and forms the reference frame for heights above mean sea level. ODN is realised on the ground by a network of approximately 190 fundamental bench marks (FBMs). From these FBMs tens of thousands of lower-order BMs were established. The network has had little maintenance for 30 years, and in some areas (mining areas for example), subsidence has affected the levelling values. In these regions the BMs cannot be relied upon to accurately define ODN.
On some of the offshore islands there are local mean sea level datums. These have no link in to ODN and must be treated the same way as the mainland levelling.
Global Positioning System (GPS) and the OSGM02TM (the height transformation between the European Terrestrial Reference System 1989 and the national height datums) is the preferred method of heighting used by Ordnance Survey. This method achieves the most accurate and uniform method of heighting.
There are approximately 500 000 'lower order' BMs still remaining. This number is reducing due to property development, road widening and so on. The BM heights shown have not been maintained for 30 years and should not be relied upon to accurately define ODN.
There are approximately 190 FBMs, which as the name suggests are our high-accuracy BMs. These are still maintained and are still used by Ordnance Survey. They form our primary height network and, as such, are our link to the Ordnance Datum at Newlyn. They are used in the creation of the orthometric to GPS height correction model (OSTN02). The FBMs are not available through this website. Access to FBM values will be considered on a case by case basis on application to Ordnance Survey." Text source; (
