In reply to IainMcT:
Almost certainly Sella Pass and Sella Towers, as others have said.
I don't know how long ago "many years" is for you, but I climbed several routes there, including the Messner route you describe, back in the mid 80's. I remember the route for three reasons. Our first attempt ended sheltering from a thunder storm in a cave/niche, one or two abseils from the ground. (I later learnt that caves/niches are not the safest shelters when lightning is around). On our second, attempt I was leading out across the big traverse on double ropes (English style) when a climber on a harder direct route that crosses the traverse managed to pass under one of my ropes and over the other (!) Took some sorting out as we didn't have a common language. We were successful on that attempt, but our sense of achievement at having climbed a "Messner" route was pulled down a peg when we realised that the Messner brothers were 17 and 15 at the time.....
