The chapel of Templars - Rosslyn (Edinburgh) - Scotland. Roslyn Chapel was one of my favorite places. Founded in the century by William Sinclair who was descended from a noble family of Norman knights. It is said to have many Knights Templar symbols.
On the Isle of Mull, in a clearing on top of the Maol Mor ridge, stand four ancient stones. Sometimes known as the Kilmore or Dervaig Stones, they are a little bit off the beaten track - but worth the effort!
