The bank... quite substantial.
The site from high ground to the approx north.... note the bank protecting this vulnerable section of the perimeter.
Looking approx westwards.... not only is there (apparently) a ‘holy well’ down there, but also the Afon Efyrnwy, outflow of ‘Lake Vyrnwy’, so beloved by tourists to the area. Note a section of defences, foreground.
The rocky ‘spine’ of the enclosure... the dark orange/red... oh, I don’t know!.... band of vegetation running across the centre of image conceals the main defensive bank.
Looking approx south.... an hour before dark, wind making photography a major pain in the proverbial. But well worth the visit.
Ffynnon Geiliog.
A well situated about 20 yards to the west of the camp on Allt Dolanog, of great popular resort on Trinity Sunday. The name (’The Cock Well’) may have been derived from the practice of cock fighting which was carried on close to the spring.

The ‘Giant’s Hall’ is a pretty obscure hillfort offering panaromic views over the magnificent Mid Walian countryside... worth the short, but very steep climb from the road for those alone, in my opinion. The relatively well preserved defences protecting the easiest approach are a bonus, so to speak.
According to Coflein:
‘A roughly oval enclosure, set in a saddle towards the summit of Allt Dolanog, c.164m by 86m, defined by an irregular plot of bank & ditch, facing rising ground, with a possible inner circuit, resting on steep natural scarps on the S. An annex is defined by a bank extending c.90m to the E. The site of a holy well lies immediately to the W (Nprn32421). The surrounding area shows traces of plough-cultivation.(source Os495card; SJ01SE2) – J.Wiles 07.01.04’.
Hmm... a holy well, too.
