We had a short break in Scotland in 2010, it being my first (and to date, only) visit to the country that forms the more politically-enlightened northern segment of the United Kingdom, and stayed in New Galloway with the intention being to get out and see the stars from the nearby forest park, one of the country’s Dark Sky sights. That sorted out our nightly activity (other than the obvious, if you know what I mean; drinking, if you don’t know what I mean) and left the days to explore the countryside where we discovered a plethora of historical sites.
Cardoness Castle was an abandoned tower house, originally built in the 15th century, and now cared for as a protected monument. On the day we visited we were the only people there and the only other car in the car park was, we think, the ticketing staff member’s. There was quite a hike up to the top of the tower and we’re not fit people but we’ve never refused a tower climbing challenge yet.
