The name Trellech literally translates to Three Stones. The Welsh for three being TRE, and one of the many known versions of the Welsh for stones being LLECH. The above signs show the three better known and used spellings of our village name, and can be found at three of the six entrances into the village. There are however 26 known spellings for our village.

In the 13th century, Trellech was larger than Chepstow. The main route between Monmouth and Chepstow ran via Trellech: the present valley road (A466) was not completed until the 1820's

Trellech was largely destroyed in 1291 as a result of a raid following a dispute over alleged deer poaching. The Black Death in 1340 and again in 1350 and, subsequently, the ravages of Owain Glyndwr and his men early in the 1400's further reduced the prosperity and in consequence the importance of Trellech. A church on this site was endowed by King Ffernwael and King Meurig, rulers of Gwent in the 7th and 8th centuries. This was probably a wooden structure. The preaching cross in the churchyard may date back to this time, and so may the Saxon font. The present building is well over 600 years old: the date of the early English Gothic stonework being between 1225 and 1272, and that of the Decorated Gothic up to 1350. When, in 1972, the weathercock was removed from the spire for reguilding, it was found to have been made in Ross-On-Wye in 1792. The original spire fell, damaging the roof of the nave. A contemporary reference attributes this to lightning and storms. The cage housing the three bells in the belfry is of a type similar to that found in other belfries constructed about the year 1700. The church was in a very neglected state at the end of the last century when it was extensively renovated and reroofed. The Belgian slates then used were replaced by Welsh slates in 1961. The chancel was replastered in 1972 and painted white. During 1974 considerable repair work has been done to the north and south aisles, and in 2001 the majority of the Churchyard dry stone wall was removed and rebuilt. New stone floors have been laid, the walls were replastered and the organ overhauled and resited. This work was found to be essential due to dampness in certain parts of the building and the discovery of dry rot. There remains a great deal yet to be done to the building if it is to be brought up to a reasonable standard. Records are held by the Church going back to the year 1692 and a complete list of Vicars and churchwardens will be found hanging by the entrance to the south isle: these date from the year 1359.

Places of historical interest in Trellech

THE THREE STONES (or TRELLECH)

These large monoliths of conglomerates, sometimes called Harold Stones, are situated in a field to the south of the village. The date of the stones is much earlier than King Harold and their actual significance is unknown.  However, some folk believe they are aligned with the winter solstice on the Skirrid Mountain, also known as "Holy Mountain of Gwent"

THE VIRTUOUS WELL

Sometimes known as St Anne's Well, this can be found in a field on the left of the road to Tintern, a little way out of the village to the east. The water is impregnated with iron and has been thought to possess curative properties.

THE TUMULUS OR TUMP

This Norman motte, some 40 feet high, is situated within Court Farm, a farmyard to the south-west of the church. There is a superstition that calamity will overtake anyone who attempts to excavate it.

THE PREACHING CROSS AND FONT

Situated in the churchyard to the South of the church. Thought to date back to the 6th or 7th centuries. In front, the font is thought to be Saxon.

SAINT NICHOLAS CHURCH

A central focal point of the village. The current building dates back over 600 years, although it is thought that a building of worship has been on the site for over 1000 years
