A real superstar amongst Scottish castles, this is Ballindalloch Castle on Speyside. Its origins date back to a Z-plan defensive tower house that was built here, probably in 1546, and it's been home to one family ever since.

@UndisScot Been several times at Ballindaloch. Beautiful castle and surroundings. It was my favourite wallpaper for years.
