Mae\u2019r capel ar Gefn y Brithdir sef y mynydd sy\u2019n gwahanu cymoedd y Darran a\u2019r Rhymni. Lan ar y cribyn mae\u2019r golygfeydd yn anhygoel gyda Phen y Fan i\u2019r gogledd, Pen y Fal i\u2019r dwyrain ac ar ddiwrnod clir, tua\u2019r De, y M\u00f4r Hafren yn pefrio yn y pellter. Mae\u2019r mynydd hwn yn nodweddiadol o\u2019r ucheldir hwn am ei fod yn rhan o Ffurfiant Pennant. Caiff ei bori\u2019n llai grymus na Chefn Gelligaer, er enghraifft, ac felly mae yno amrywiaeth ehangach o lystyfiant i\u2019w weld yn cynnwys sawl math o wair: Deschampsia flexuosa, Festuca ovina a Nardus stricta. Yn y mannau creigiog ac ar y llethrau serch mae grug yn tyfu.<\/p>\n\n

Yn ogystal mae yno ardal fach o Ddiddordeb Gwyddonol o ganlyniad i \u201camrywiaeth a dwysedd cymharol y rhywogaeth o gorlwyni (llys y llugaeron)\u201d sy\u2019n tyfu yma (Cyngor Cefn Gwlad Cymru).<\/p>\n<\/blockquote>\n\n

Yn \u00f4l y llyfr The Gelligaer Story<\/em>, \u201ctynnwyd to Capel y Brithdir ymaith ym 1955, o ganlyniad i halogiad parhaus\u201d ac arweiniodd hwn at ddinistriad llwyr y capel ym 1960. Yn ystod y cyfnod hwnnw, daethpwyd o hyd i groes Geltaidd wedi ei chladdu y tu fewn i un o furiau\u2019r capel. Wedi ei dyddio rhywbryd rhwng y 7fed a\u2019r 10fed Ganrif, caiff ei chadw erbyn hyn yn eglwys Santes Gwladys ym Margod. <\/p>\n\n

Yr hyn sydd ar \u00f4l o Gapel y Brithdir yw llwyfan sy\u2019n dangos lle safai capel a chopi o groes Geltaidd i ddynodi ei ddechreuad hynafol. Mae\u2019r fynwent sy\u2019n amgylchynu\u2019r capel yn frith o gerrig beddi talsyth ac eraill sy\u2019n gorwedd ar lawr. Mae\u2019r geiriau arnynt yn Gymraeg ac yn Saesneg ill dwy. Mae\u2019r gwaith yma\u2019n hir ac anniben, ac ymestyn tua\u2019r nen y mae cangenau\u2019r bedw arian ifainc tra bod eraill yn sefyll yn dalsyth yn gwarchod hen fynedfa\u2019r capel. Yn yr hen oesoedd byddai amgylchynwyd mannau sanctaidd \u00e2 ffin gron. Yn yr un modd \u00e2 Chapel Gwladys, os cymerwch yr amser i edrych yn ofalus, byddwch yn sylwi bod crymedd cyfarwydd yn y fan hon hefyd. <\/p>\n\n

Ychydig fetrau i ffwrdd o Gapel-y-Brithdir saif copi o Garreg Tegarnacus. Safodd yma yn y 7fed Ganrif, ac o bosib hyd yn oed yn gynharach. Mae\u2019r gwreiddiol nawr wedi ei chadw yn Amgueddfa Genedlaethol Cymru yng Nghaerdydd.

Mae yno sawl llwybr i gyrraedd Capel y Brithdir ond dydd Mercher yr 17eg o Ragfyr byddwn yn cynnal taith dywys i\u2019r capel yn gadael o Barc Cwm Darran am 9:30 y bore. Dewch i fwynhau w\u00e2c cyn y Nadolig yn ardal Cefn Brithdir a Chwm Darran. Bydd y w\u00e2c ryw naw cilometr o hyd a bydd yn cynnwys llwybrau, traciau a gweundir agored.
