The Carningli throne

I have been looking again at this strange "seat" on the south side of Carningli, just a few yards west of the highest "ty unnos" ruin on land belonging to Gelli.  It is nestled in the lee of a slight ridge, which means it's quite sheltered from the westerly winds, and it commands a fantastic view down into the valley.  But what on earth is it?  The "seat" is a massive flat slab of rock big enough to seat two people, and it's incorporated into a ruinous small building that must have had original dimensions of c 2x3m.  Just the remnants of the walls are left.

I thought at first that this might have been the toilet or "ty bach" -- but that's extremely unlikely.  For a start, it's on the windward side of the house, and it's above the catchment for the spring used for the cottage's water supply.  And a toilet has no room for a great flat slab of rock -- what you need is a wooden seat high enough to allow a bucket to be placed beneath it. 

I think it might have been a sort of mini-scullery or dairy, with the stone slab used for storing and cooling milk, butter, cheese etc.  Very strange.  More romantically, let's just think of it as a throne, designed by nature (and with a little help from the locals) for sitting and enjoying the view.
