Mae\u2019r pentref yn uchel yn nyffryn yr Afon Alyn wrth iddi lifo i gyfeiriad y gogledd o<\/p>\n\n\n\n

Fryniau Clwyd. Lleolir yr Eglwys a\u2019r pentref ar fin gogleddol ochr y dyffryn yn agos at y man lle mae aliniad newidiol yr afon wedi creu esgair. Y tu \u00f4l i\u2019r aneddiad, mae\u2019r llwyfandir calchfaen tonnog yn codi\u2019n raddol.<\/p>\n\n\n\n

Mae gan y pentref hanes hir a chyfoethog. Mae darganfyddiadau o Oes y Cerrig, sy\u2019n awgrym o feddiannaeth miloedd ar filoedd o flynyddoedd yn \u00f4l, wedi cael eu canfod yn yr ogofau yn y pentref. Caiff yr aneddiad ei grybwyll am y tro cyntaf yng Nghofnodion Treth Norwich 1254, a chaiff ei gofnodi fel \u2018Sancto Garmano\u2019.<\/p>\n\n\n\n

\"Coed<\/figure>\n\n\n\n

Erbyn 1314, mae\u2019r pentref bellach yn cael ei adnabod yn \u00f4l ei enw cwmwd \u2018Thlanharmon in Yal\u2019. Yn \u00f4l pob tebyg, Llanarmon-yn- I\u00e2l oedd prif ddinas y cwmwd I\u00e2l, a bod cysegriad yr eglwys i Sant Garmon yn adlewyrchu hyn, yn ogystal \u00e2 sylfaen Ganoloesol gynnar iawn.\u00a0 Mae\u2019r fynwent, gellir darllen mwy amdani yn y cofnod ar Eglwys Sant Garmon, wedi\u2019i chodi\u2019n uchel ac mewn si\u00e2p cylch, sy\u2019n sicr yn awgrymu dyddiad cyn y Goncwest, ac yn bosib iawn, sylfaen cyn Cristnogaeth.<\/p>\n\n\n\n

Mae\u2019r rhwydwaith o ffyrdd a lonydd o amgylch y pentref yn ddifyr iawn.\u00a0 Ymddengys, er yr addasiadau dros y blynyddoedd, mai\u2019r eglwys oedd y canolbwynt ar lwybr rhwng Abaty Glyn y Groes<\/strong> i\u2019r de a\u2019r safleoedd eglwysig Abaty Dinas Basing a Ffynnon Santes Gwenffrewi yn y gogledd.<\/p>\n\n\n\n

Yn yr unfed ganrif ar hugain, mae tai yn yr aneddiad yn gymysgedd o fythynnod o\u2019r ddeunawfed ganrif \/ y bedwaredd ganrif ar bymtheg a thai modern. Mae gan lawer o\u2019r bythynnod gerrig dyddio, a gweler y garreg gynharaf o 1749 ar Lwyn Onn\u2019. Mae pentref Llanarmon wedi cadw ei Swyddfa Bost a\u2019r dafarn Raven Inn a adeiladwyd ym 1722. Mae\u2019r hen ysgol (a adeiladwyd ym 1777) bellach yn cael ei defnyddio fel Neuadd yr Eglwys. Mae\u2019r Eglwys yn dal ar agor fel man addoli, yn ogystal \u00e2 Chapel Calfinaidd Cymraeg Bethel.<\/p>\n\n\n\n

Mae pentref Eryrys yn hen bentref mwyngloddio, hanesyddol yng nghymuned Llanarmon-yn-I\u00e2l. Mae sawl ffynhonnell yn awgrymu bod yr enw\u2019n deillio o Erw Yrys neu Erw Gyrys.<\/p>\n\n\n\n

Mae\u2019r pentref wedi\u2019i adeiladu ar fryn carreg galch Bryn Alyn a gellir gweld llawer o gerrig brig calchfaen gerllaw.<\/p>\n\n\n\n

Mae tystiolaeth yn dangos bod mwyngloddio ar raddfa fach wedi dechrau yma yn y drydedd ganrif ar ddeg, ond dim ond yn ystod misoedd sych y flwyddyn. Roedd y gwaith hwn yn cael ei wneud gan ffermwyr lleol yn bennaf tan 1735 pan gymerodd Yst\u00e2d y Grosvenor drosodd ar \u00f4l cael eu hatal gan \u2018hen ddeddfau mwyngloddio\u2019 ers blynyddoedd lawer. Cloddfa Westminster oedd fwyaf cynhyrchiol yn yr ardal ac roedd yn cael ei chloddio am blwm a sinc.<\/p>\n\n\n\n

Mae pentref Graigfechan<\/strong> wedi\u2019i leoli ar gornel dde-orllewinol ardal Bryniau Clwyd.\u00a0 Gyda Gwarchodfa Natur Graig Wyllt i\u2019r gogledd a choetiroedd collddail helaeth, mae\u2019n aneddiad cnewyllol ar ymyl y ffordd gyda bythynnod o\u2019r ddeunawfed a\u2019r bedwaredd ganrif a\u2019r bymtheg, capeli, a thai o\u2019r ugeinfed ganrif, wedi\u2019i leoli o amgylch bryn calchfaen amlwg.<\/p>\n\n\n\n

Mae Graigfechan yn bentref sy\u2019n llawn hanes. O olion traed Celtaidd hynafol i ddechreuadau amaethyddol canoloesol, mae\u2019r pentref yn adrodd hanes difyr drwy ei fythynnod carreg ac Eglwys y Santes Fair.<\/p>\n\n\n\n

Mae Graigfechan yn croesawu ei wreiddiau hanesyddol a thawelwch natur, gan gynnig mynedfa i Fryniau Clwyd. Fel naratif hanesyddol byw, mae\u2019r pentref yn taro cydbwysedd cyt\u00fbn rhwng traddodiad a chynnydd, gan wahodd ymwelwyr i ymhyfrydu yn ei swyn arbennig. Mae gan y pentref wefan ddifyr<\/a> a gallwch ddarllen mwy am ei hanes yno.<\/p>\n","protected":false},"excerpt":{"rendered":"
