Rohallion Castle (2)
So, having faithfully quoted the <a href="http://www.ancientmonuments.uk" rel="noreferrer nofollow">www.ancientmonuments.uk</a> website's opinion that Trochrie Castle was not a Z-plan castle because the mid-16th century was a bit early for tower-houses of that design, here, just three and a half miles to the west, is a small 16th century Z-plan tower-house!

(Rohallion is very similar in size and design to Terpersie Castle in Aberdeenshire, also a Z-plan tower-house, and known to have been built in 1561.)

The oblong central block of the castle, which is roughly orientated east and west, is 27 feet long, by 20 feet wide and its walls these days stand no more than 4 feet high.  The opposing corner towers, that give it its Z-plan, are both round and are only 12 feet in diameter.  If you subtract the width of the walls on either side, there must barely have been room to swing a cat around inside!  This photo is taken from the east and shows the north-east tower and the east gable of the main block, with a doorway in it.

There is a recess on the inside of the west gable, hidden under the tree, that appears to have been a fireplace.  No vaulting is visible, and there is nothing to indicate the position of a staircase.
