Being working on the memory banks and looking at very very old maps which show the actual Castle about 100yds Northwest of the mouth of the burn which runs thru cemetary.I remember playing on a small quarry stone and mortar tower when a kid.This was the Campbeltown Volunteers battery.
It was a castellated tower and had a room on ground floor which was the powder store.There was an area of hardstanding fronted by a wall a few feet high running up towards what I think was Ollars house. This was the hardstanding for the cannons.The old tramp guy with the long hair (cant remember his name) ..Charlie Greenfellow?? used to sleep in there,before my time of course.There was also a flagpole on the site to the South West.
If you keep an eye on Russells Carrolls site at
http://campbeltownloch.com/news.php you will find "coming soon for your viewing" a fantastic photo showing the area with a line up of cannons on the hardstanding.In the grounds of Ollars house there was also a lighthouse incidently.The map I refer to is 1700 to 1800 as it shows the other Castle up Askomil (which was a Mac Donald residence )and is associated with Castle Muller at Smerby. So there......
The old maps incidently show the location of the very old Church located in the old Cemetary eg Kilkerran Church which has succumed to time and virtually vanished. Those maps or a link to them will also be on Russells site in time. Many old ruins are also shown eg Ballintuiney township near to Achenhoan Farm the location of which was unknown to me.
