Dun Dubh is one in a line of Hillforts that top the hills above Ford and on towards Loch Awe (which itself has a number of cranogs).
There's not much left to see up there by the way of remains. Just a possible entrance and plataux. But the views us Lock Awe and over towards Jura are truely stunning.
Apparantly, Samhain fires were light on top of Dun Dubh until quite recently.
Samhain fires were lit on top of this ruined fort until recent years, as some local folk will tell you. These Halloween fires (done to celebrate the old New Year) were stopped a short time after the owner of the Auchinellan Estate (on whose land Dun Dubh is found) took exception to them and, for all intent and purpose, deemed them a fire hazard! The lady in question who inherited the Estate was in fact a devout christian who took exception to the local "pagan" goings-on; contrary to the beliefs of the previous Estate owner.
The fires here were also related to the linear cemetary at Kilmartin. Here the giant tombs all line up & point to Dun Chonallaich, behind which hides Dun Dubh. When the Halloween fires were lit on top of this, the glow from behind the great pyramid of Chonallaich all the way down to Valley of the Kings, was spectacular! One wonders just how long the local people had been doing this...
