A puzzle for which the answer is a letter. This shape must then be placed onto 4 different nets of different 3D shapes. Identify which shape doesn’t follow a rule (the R revealed in the previous shape cannot be consecutive to a square). The letter associated with the offending net needs to be taken out of an anagram, which turns out to be a book quote ending in “said ____” and converting the name to a number gives co-ordinates. Finding the landmark at the co-ordinates and the year it was completed should give two numbers (30N 16W gives 3016, and year in AD four digit number). Take each of these numbers away from each other and the difference should be shared by one other landmark in the same country. That landmark can be bought from Ebay and if the number is used as a coupon, I will send the first stone tablet.
