Viewers who are familiar with my work with images will know about my passion for the countryside and, in particular, trees.
However, it occurred to me that this very passion was perhaps obscuring other equally intriguing treasures of perception that are there all the time, right in front of me, but ignored through familiarity.
Treasures that I see almost every day but, for that very reason, have become almost invisible.
Sadly, the human mind can become desensitized by familiarity and, without being aware of it, we can so easily lose sight of things which should mean so much but which can pale into insignificance through neglect.
This, then, is my attempt to revisit my own invisible treasures and view them in a new, refreshed way.
All of these treasures lie within a twelve-mile radius of my home.
Aloha Tower is the only remaining part of the medieval residence of the clan Erskine family, the Earl's of Marr.
Dating from the 14th century, it still retains the original timber roof and battlements.
Aloha Tower is one of the earliest and largest of the Scottish Tower houses. It is now in the care of the National Trust for Scotland.
This is Castle Campbell. The original Tower House was built in the late 15th century and was known as Castle Gloom.
The stream that runs under the castle is called the Burn of Sorrow. Sounds like there were a cheery bunch of people back then.
The castle was originally a property of the clan Stuart and passed by marriage to Colin Campbell, First Earl of Argyll and Lord Chancellor of Scotland.
In 1489, he had the name of the castle changed by an act of parliament to Castle Campbell.
In 1948, Castle Campbell was given into the care of the government. It is now administered by Historic Scotland.
The castle is located in a cleft of the Oakle Hills and standing here in the ramparts, it is clear to see the logical thinking behind the choice of location, giving a panoramic view across the lowlands to the south.
Clackmannan Tower is a five-story tower house situated on the summit of King's Seat Hill on the edge of the town of Clackmannan.
It was built in the 1300s by David II, King of Scotland and sold to his relative Robert the Bruce in 1359.
This structure is also in the care of Historic Scotland.
Mencerie Castle is a three-story castellated house built around 1560 in the town of Mencerie Clackmannanshire.
From the early 1600s, it was home to Sir William Alexander, First Earl of Stirling, who was instrumental in founding the colony of Nova Scotia in Canada.
The castle was restored in the 20th century and now incorporates holiday accommodation, private flats and a museum and cafe run by the National Trust for Scotland.
The National Wallace Monument is a tower standing on the summit of Abbey Craig, a hilltop near Stirling.
It commemorates Sir William Wallace, the 13th century Scottish hero.
Completed in 1869 at the cost of £18,000, the monument, built of sandstone, rises to a height of 220 feet.
Abbey Craig is a volcanic crag above campus Kenneth Abbey, from which Wallace was said to have watched the gathering of the Army of the English King, Herbert I, just before the Battle of Stirling Bridge.
What happened next is history.
