The tower of St Peter’s stands as a way-marker by which people have navigated the Vale of Clwyd for centuries. It stands too as a testament to the faith by which people navigate their lives. 

There is a rich and fascinating history relating to St Peter’s. The present Church was built by John de Grey in 1310, following the erection of Ruthin Castle by his father, Reginald de Grey in 1277. For some time before this Ruthin had been the home of a nunnery and a priory. From 1310 to 1536 St Peter’s was a Collegiate Church served by a Warden and seven priests.
Following the dissolution of the College, its work was restored on a new pattern by Gabriel Goodman (1528-1601), a Ruthin man who became Dean of Westminster in 1561. Goodman re-established Ruthin School in 1574  and refounded the Almshouses of Christ’s Hospital, together with the Wardenship of Ruthin in 1590.

St Peter’s is not a museum though, it is active in the life of the town pointing beyond itself to the love of God. 

Saif twr Sant Pedr fel arwydd ffordd y mae pobl wedi llywio Dyffryn Clwyd ynddo ers canrifoedd. Mae’n sefyll hefyd fel tyst i’r ffydd y mae pobl yn llywio’u bywydau drwyddi.

Mae yna hanes yn ymwneud â St Peter’s . Adeiladwyd yr Eglwys bresennol gan John de Grey ym 1310, yn dilyn codi Castell Rhuthun gan ei dad, Reginald de Grey ym 1277. Am beth amser cyn hyn, roedd Rhuthun yn gartref i leiandy a phriordy. Rhwng 1310 a 1536 roedd Eglwys Sant Pedr yn Eglwys Golegol a wasanaethwyd gan Warden a saith offeiriad.
Yn dilyn diddymiad y Coleg, adferwyd ei gwaith ar batrwm newydd gan Gabriel Goodman (1528-1601), dyn o Ruthin a ddaeth yn Ddeon San Steffan ym 1561. Ail-sefydlodd Goodman Ysgol Rhuthun ym 1574 gan ail-gartrefu Elusendai Ysbyty Crist, ynghyd â Wardeiniaeth Rhuthun ym 1590.

Nid amgueddfa yw Sant Pedr serch hynny, mae’n weithgar ym mywyd y dref gan dynnu sylw y tu hwnt i’w hun at gariad Duw.
