From memory it's a scheduled monument so couldn't be removed.

And it is played over on the 11th, 14th and 15th. The decision as to whether to lay up short or try to carry it needs to be made on both 11 and 15 and in both cases laying up leave a blind mid-iron approach, whilst carrying it leaves a short approach with a wedge. There's also a wall along and close to the left of the 11th green.
During BUDA at least one of my opponents (can't remember who, also had a ball lying up against the wall running down and close to the left of the 13th green. The wall at the back (and to the left) of 10 green can also often be in play. As can the wall behind the 1st green, and on the left of the 6th fairway.
I've never seen the wall behind 17 in play but imagine it could be.
The old lifeboat house to the left of the green on the 1st on Balcomie can also be in play and the perimeter wall on the right of 7, 8 and 9.
