Greenknowe Tower

Greenknowe Tower "Greenknowe Tower is a 16th-century tower house, located just west of the village of Gordon, in the Scottish Borders. Although a roofless ruin, the stonework of the tower is well preserved, and represents a fine example of a later tower house, built more as a residence rather than as a place of defence" (from wikipedia)

Nice wee tower, you can go up and down the spiral stairs and get some nice views from the top.

Locals claim it is "the most haunted place in the area" but there doesn't seem to be much more said than that. Didn't see/hear any ghosts so can't confirm...

Hume

Hume Castle

Hume Castle is the modified remains of a late 12th / early 13th-century castle. Nice castle folly in a quiet scenic area.

"Hume Castle was used as a beacon to warn of English invasion throughout the medieval period. During the late eighteenth and early nineteenth centuries it performed the same function but was now on the alert for an invasion by Napoleon. On 31 January 1804 the alarm was raised when a fire from charcoal burners on nearby Dirrington Law was mistaken as a beacon. When the Sergeant in charge of Hume lit his own beacon, the result was a chain initiation across the Scottish borders and the mobilisation of a 3,000 strong force. This became known as the 'Great Alarm'." (from castlesfortsbattles.co.uk)

The surrounding field often has sheep in it, so don't go in with your dog off lead! The gate may appear locked but you just need to lift the latch and slide it along, be sure to close it to keep the sheep out (and obviously close the field gates to keep the sheep in!)

If you take a wander down to the Hume War Memorial, you'll also see the memorial horse sculpture and also a bizarre Wickerman-esque figure lurking in the trees!

Neidpath

NEIDPATH

Went for a walk along the Tweed passed Neidpath Castle, across the Neidpath Viaduct and then through the old train tunnel!

"Neidpath railway tunnel is a nearly half-mile-long abandoned train tunnel situated close to the town of Peebles and was often known as the Peebles Tunnel. William Scott was contracted to construct the tunnel as part of the Peebles-Symington extension. The tunnel was once considered the most notable feature of the rail line and was built under South Park Wood to emerge within an earshot of Peebles.

The all-consuming and overwhelming darkness of the tunnel can be eerie. Along certain sections inside there is no natural light and you can see neither the entrance nor exit. The tunnel was also used during World War II to transport raw materials for the war effort. It’s believed that it was also the hiding spot for the royal train when the king and queen surveyed damages done in Clydebank following a Luftwaffe bombardment, although this has been disputed" (from Atlas Obscura )

The castle isn't open to the public but the Viaduct and the tunnel are open all year round - you may want to bring a torch for the tunnel!
