Sounds as if it is the Iona community movement rather than Iona the place that is most important to you. And indeed many of the activities you describe can, and are, not conducted in Iona the place. And therefore I presume the community could be based in places other than Iona and would still be special to you.
For me it is the opposite - I have no engagement, nor desire for engagement with a christian religious community. However Iona the place is very special due to it's end of the earth feel and that it makes humanity seem insignificant in the context of nature. I remember in Iona Abbey thinking that I rather liked being in churches but massively prefer them while empty or next to empty rather than full of a worshiping community. That time I was just about the only person in the place, except for a couple of rather accomplished musicians (one was a flautist, the other a cellist) playing/practicing quietly - it was a special moment, but not a religious one.
Oh, yes, the Abby is indeed special, and atmospheric, Prof.
All the more so when one realises that it's in its' present state thanks to Mcleod, who took a group of trainee ministers and unemployed folk from Govan with little knowledge of building, and started rebuilding the Abby, and, at the same time, creating the community...in a sense the Abby wouldn't exist in its' present state (Iona having its' own, rather beautiful, parish Kirk) without the concept of the community.
Incidentally, a couple of years back, archaeologists from Historic Scotland found what is almost certainly Columcille's cell, not far from St Oran's Cross.
It doesn't get any more significant than that!
