I'm a tad bemused by this one. I have a complete grid, the period and the instruction. I've got a pair of coordinates that appear to locate a quite specific place but I can't find anything very interesting about it or anthing about the country it's in that fits the brief. The Wikipedia entry on the location is very slim. I've twiddled the coordinates in case I'd chosen the wrong instance of a letter that appears twice in a solution, stared at the grid for something rectangular, shaped like the item in the instructions and haven't found anything.
Hey ho, more grid staring I suppose.
