There's not a lot left of this ancient chapel, once a resting place for pilgrims to St Andrews in Fife, on the far side of the Firth of Forth.

In these photos you can see that the ground pattern of some of the walls continues over the path to the right and is cleverly shown in contrasting slabs, to indicate the full extent of the original buildings.

Another view showing the odd shape of the building, the sides not being parallel.
