Chirk is a market town, population approximately 4500, on the southern boundary of Wrexham Borough County, on the north bank of the River Ceiriog.
The Langollen Canal crosses the Ceiriog by aqueduct, with a railway viaduct running parallel running north, to the west of the town.
Chirk Castle stands on the hill to the west, and this category represents websites for the area around the remains of Offa's Dyke,
but those for areas further west are listing in the Glyn Ceiriog locality.
The village south of the Ceiriog, is named Chirk Bank, in Shropshire where websites are represented by the Weston Rhyn category.
Although the town is served by the B4500 and B5070, it is bypassed on the east by the A5, from Oswestry towards Ruabon.
North of the town the A5 heads west up the Langollen Valley, on the south bank of the River Dee across the WBC boundary to Langollen.
Until there are sufficient websites to justify a separate category, this locality includes the village of Froncysyllte,
and the area east to the confluence of the River Ceiriog with the River Dee.
Websites for areas north of the Dee should be listed in the Ruabon locality.
This category is for websites exclusively about the village of Glyn Ceiriog and the Ceiriog valley within the
county borough of Wrexham, as the Ceiriog flows from the hill-top west boundary at Cadair (784 m)
through the village of Llanarmon (Dyffryn Ceiriog), and along the B4500 on its north bank
through Tregeirog (Foel Rhiwlas), Pandy, Dolywern, and Pontadog, to Chirk.
Overton is a village in the south east of Wrexham Borugh County, on the east bank of the River Dee, west of Erbistock on the west bank.
The A495 from Penley to Ruabon, crosses the Dee at Overton Bridge north of Erbistock.
This category is for website from or about this locality, to Knolton Hall, the south border along Shell Brook to
the hamlets of Knolton Bryn and Knolton on the A528 to Ellesmere, and Lightwood on the A539 Penley.
Websites for Hanmer and further south east are included in the Bronington category.
Until there is a separate category, websites for Bangor-on-Dee are included here, whereas those for areas west of the River Dee are included in the Ruabon locality.
