On the edge of Edinburgh, between the world-famous Rosslyn Chapel and the rather less attractive Edinburgh city bypass, stands a stone tower in the middle of a field which is well worth a look as part of a countryside walk.

Dryden Tower is a three-story structure built from sandstone that was originally part of the sizeable Dryden Estate, once the powerbase for the influential Lockhart family. Even though the tower predates Lockhart, it is more likely that George Mercer, the estate’s subsequent owner who resided there until the mid-1840s, was the one who actually built it.

While the exact date it was built is unknown, Ordnance Survey first mentioned the tower in one of their maps in 1852, so it’s thought to have been built somewhere between that date and the time when George Mercer took ownership of the nearby Dryden House (now demolished).

So what exactly was the original purpose of Dryden Tower? Again, that’s unknown but it was likely either a rest area for the landowner after a day spent roaming around the estate, a memorial, or a folly with no particular purpose other than being eye-catching. Nonetheless, it’s an impressive sight, being constructed of a light-coloured sandstone and with mock fortifications around it’s walls, which are, for an unknown reason, in a semi-circular shape.

Dryden Tower

As already mentioned, the tower was most likely built as a Victorian folly so it doesn’t have much of a historical interest, but due to its age it has been designated as a category B listed building by Historic Environment Scotland.

It’s no longer possible to enter Dryden Tower as it has been cordoned off by a large metal barrier, which is a shame as a major restoration in 2014 restored it back to its former glory after years of neglect when much of the surrounding land was used for other works.

Like most of the collieries in the Lothians, the Bilston Glen Colliery has long since vanished and in its place is a nature reserve which offers a much-needed habitat for wildlife as well as giving locals a lovely spot to escape the noise of the surrounding industrial areas. The majority of the remainder of the former Dryden Estate is farmland, which means that seeing the tower is possible, but only by keeping to a designated path.

If you were able to get inside you’d find that it’s possible to climb a staircase all the way to the top which presents stunning views of the Midlothian countryside – something that will hopefully be permitted again sometime in the future.

Still, at least visitors can see the tower as they follow the walking route mentioned below which starts in the lovely village of Roslin and heads to the extremities of Loanhead and Bilston, taking in the amazing views from the Bilston Glen Viaduct which is another historic landmark that’s worth seeing.

Battle of Roslin Monument

Walking Route

Distance: approx. 4 miles. Time to complete: approx. 2 hours.

Starting from the war memorial in Roslin, walk along Manse Road for 0.6 miles till you reach Dryden Farm, where you’ll see a monument to the Battle of Roslin, then follow the cycle path signed Loanhead for 0.5 miles till you reach the Bilston Glen Viaduct.

Continue over the viaduct and take the left turn along the railway sidings that were once used for the Loanhead Colliery. Head through woodland for 0.5 miles and take the path to the left, signed for Bilston. At this point, there’s a steep slope where you can just about see Dryden Tower through the trees.

Continue around the back of the Bilston Glen industrial estate and follow the rough track to the Bilston Burn which will lead you into a woodland. Follow the sign for Roslin, cross a small stone bridge, and take the left path which leads out of the woods into fields.

Once you’ve veered around the first corner of the field you’ll be close to Dryden Tower so if you have a camera, now is the time to take some photos. Continue down the double-fenced path past the tower (take care because it’s very muddy) till you reach the entrance to Langhill Farm.

Take the left path through the gate down a grass track for 0.2 miles, then take the right-hand path up a line of trees bordering fields. Turn right onto a 4-way junction and follow the path back to the Battle of Roslin Monument. Return on the inbound route back to the Roslin War Memorial.

Dryden Tower

The Highlights

1: Dryden Tower is an interesting landmark but you’ll also see two more historic points of interest along the way. The first is the Battle of Roslin Monument near Dryden Farm, which is a tribute to a relatively unknown battle in 1303 when English invaders were defeated. The second sight, the Bilston Glen Viaduct, opened in 1874 and is notable for its lattice ironwork and scenic viewpoint.

2: If you’re looking for an enjoyable walk in the countryside that’s just a stone’s throw from the always-busy Rosslyn Chapel, you won’t go far wrong with this route between Roslin, Bilston, and Loanhead. The walk takes visitors through fields and woodlands as well as a nature reserve, yet it’s just 1.5 miles from the city bypass.

Visiting Tips

1: Dryden Tower is an interesting landmark but it’s located in the middle of a field which you can only see from between a double fence that circles the perimeter. The tower is around 250 feet from the nearest fence, so if you want a close-up view, I recommend taking binoculars (link to binocular reviews) or a camera with a decent zoom lens.

2: If you’d like to extend this walk I recommend heading to Roslin Glen and following the picturesque footpath that follows the River North Esk. This footpath is a real gem and offers some amazing views, such as Wallace’s Cave. The AllTrails website has a good overview of the 5-mile circular route, as does the Ordnanceance Survey. See the’maps section near the top of this page to get access to the entire collection of OS Maps.

3: The path that runs along the edge of the fields near Linghill Farm becomes a muddy quagmire after a rainfall, so this is one walk where you’ll need to wear wellies or waterproof walking boots (link to boot reviews). The rest of the paths are okay for walking, but only the section from the viaduct to Roslin (right-hand side on the map) is suitable for a bike.
