There is an excellent article on Visegrad in the weekend supplement of the Financial Times by Alec Russell: “Unforgiven, unforgotten, unresolved: Bosnia 20 years on.”
I visited the place in 2005 with a friend and found it, more than most towns in RS, enveloped in its own time warp. I particularly remember the postcards of monasteries and churches.
Versions of the horror that unfolded there are also told in Chuck Sudetic’s book Bood and Vengeance. There was also a Channel 4 story on the bodies unearthed by the dam repair over a year ago if memory serves.
