I have been wanting to build a rocky outcrop island in the Micropolis bay for some time, and have been collecting together a few Big Ugly Rock Pieces (6082) that I got in a mixed lot recently. It also contained a load of other random slopes, bricks and tiles in old dark grey, so I thought I would use these as the basis for my island.
I envisaged high cliffs with tiny little houses nestling on ledges, just like you see in some Mediterranean countries. And I wanted to top it off with a fortified Monastery, but didn’t quite have enough parts in tan, or cone pieces for turrets, until I got the 2016 Christmas Build Up set, which had a couple of tiny castle builds as the models.
So finally I was able to finish off Holy Island:

There is a lighthouse on the seaward side to prevent ships from foundering on the rocky cliffs.

Here are a few details of the tiny houses built into the rocks.

Unlike the smaller 1/4-block modules, I used 16×16 baseplates underneath as well as the top plate, as I think they will make this bigger module, built as one piece, a bit more stable. I usually just use a few 2×6 and longer plates to cover the edging on the smaller blocks.
