This cache will take you to the site of Fast Castle ("Fast" as in the old sense of "secure" - although there is a ton of irony there!). The place is very dramatic and inspired Sir Walter Scott to use it as the location for "Wolf's Crag", the ruined tower which was the home to the impecunious Master of Ravenswood in The Bride of Lammermuir. Ravenswood's doomed pursuit of Lucy Ashton provided the inspiration for Donnizetti's Lucia di Lammermoor.
The reality makes Scott's and Donnizetti's romantic imaginings pale a bit. There was a fortification here at least as long ago as the early Iron Age. There has been a castle here since at least the 14th century when the English took it after Bannockburn. (The young Dunbar took the castle back for the Scots in 1410.)
In 1513, Sir Robert Ker, the warden of the castle was murdered by 3 Englishmen: "Lilburn, Starkhead and Heron the Bastard". Lilburn was captured. Starkhead was murdered by a contract assassin hired by the Kers. Heron the Bastard escaped. But James IV of Scotland had his brother, Heron of Ford thrown into the dungeons of Fast Castle along with Lilburn, where they starved to death. Meantime, in September of that year, during the campaign that ended at Flodden, James IV lodged at Heron of Ford's castle and - what he has done to her husband apparently notwithstanding - enjoyed the favours of Heron's wife.
The castle was repeatedly burned and pillaged by both sides in the relentless border wars. It passed into the ownership of the Homes and finally Logan of Restalrig. It was forfeit, along with all the rest of the Logan estate, when the Gowrie conspiracy collapsed. Collapsed - and so did Fast Castle. By the early 1600s it was a ruin and things have gone from bad to worse since, aided by a lightning strike in the 1870s which brought down the last standing tower. Not much now stands. But what there is is evocative enough and may draw a novel or an opera from you.
To get there take the A1 and turn off onto the A1107. A single-track road is signed to Dowlaw Farm and takes 2 miles across the fields to the sea to end at a parking area. There is a distinct sign-posted path to Fast Castle Head. The walk there and back to the car is about 1.5 miles and there is a drop (and re-climb on the return) of around 400 feet.
The last stages of the walk may be challenging. The path skirts a steep gully dropping to the sea. Shortly afterwards you must cross a narrow neck linking the incipient stack to the shore. The crossing is protected by - very rusty! - chains and iron posts. Once on Fast Castle Head there are steep drops on all sides. Keep children and animals on a very short rein!!
This is - it would have to be, wouldn't it? - a climbing venue. As you cross the neck, the drop to your right is "Abseil Gully", the route which climbers take to drop down to the base of the cliffs on ropes slung round the guard posts. (Jack's no longer sure he'd trust the posts as much as once he did....) If you look south down the coast you will see "The Souter" a sea stack among fins of rock sticking out to sea. There may be climbers at work there too.
If you have the head for it, walk out along the stack as far as you can and then look back at the cliffs to watch the guillemots whirring out over the sea or back to the crags on their "clockwork" wings, for all the world like Scottish penguins.
Enjoy the position and the views.
