Touchstone Labyrinth in Blackmuir Wood, Strathpeffer. Illustrates the different rock types and geological ages found in Scotland. And the labyrinth is based on Celtic and Pictish designs. Information boards identify the rock type for each boulder and explain how alignment of the "arms" is related to events such as the solstice. Really just a spiral.
Llandyfeisant Church, Llandeilo. One of Wales' most peaceful churches, Llandyfeisant can only be reached across fields or up a private dirt track. The site dates back to pre-Christian times and it has not been used for services since 1961.
