Bavelaw Castle
Bavelaw Castle is a ruined tower house nestled on the southern fringe of the Pentland Hills in Midlothian, Scotland. It sits in a remarkably secluded position near the edge of Threipmuir and Harlaw Reservoirs, giving it an atmosphere of quiet isolation that is rare even by Scottish standards. Though modest in scale compared to some of the great fortified houses of the Lothians, Bavelaw has a particular charm rooted in its intimacy with the surrounding moorland and water. The castle is a Scheduled Ancient Monument, recognised for its historical and architectural significance, and while it is not open to the public as a staffed attraction, it can be approached on foot and appreciated as a picturesque ruin within one of Edinburgh's most beloved outdoor escapes.
The origins of the castle date to the late sixteenth or early seventeenth century, built by the Murray family who held the lands of Bavelaw for several generations. The Murrays were an influential Lothian family, and the castle served as their laird's residence in this elevated, pastoral corner of the region. The tower house style was typical of Scottish landed gentry of the period — functional, defensible, and built to last from the local rubble stone of the Pentland landscape. Over subsequent centuries the castle fell out of regular use and gradually became the roofless shell visible today. While it lacks the dramatic sieges or royal associations of larger Scottish fortifications, its story is one of quiet domestic aristocratic life against a backdrop of Scottish rural history stretching back to the Border troubles of the late medieval period.
In person, Bavelaw Castle presents itself as a compact, L-plan tower ruin, its walls still standing to a reasonable height in places but open to the sky. The masonry is rough-hewn local stone, now heavily weathered and colonised by moss and lichen, lending it an almost organic quality as though it is slowly being reclaimed by the hillside. The setting is arresting: the castle stands close to the reedy southern margin of Threipmuir Reservoir, with rushes and marsh grasses at its feet and the open water shimmering beyond. On still days, the reflections in the reservoir and the distant call of curlew or lapwing make the place feel genuinely timeless. Wind off the Pentlands can make it a bracing spot even in summer, but this only adds to the sense of remote, elemental Scotland that the site exudes.
The surrounding landscape is among the finest accessible countryside within easy reach of Edinburgh, which lies only around ten miles to the northeast. The Pentland Hills Regional Park encloses the area, and Bavelaw sits at a junction point between the agricultural lowlands and the open heather moorland that sweeps up toward the higher Pentland tops. Threipmuir and Harlaw Reservoirs were constructed in the nineteenth century to supply water to Edinburgh, and together with the wooded policies around them they now form an important wildlife habitat. Red kites, which were reintroduced to the area, can sometimes be seen quartering overhead, and the reservoirs attract wildfowl throughout the year. The nearby village of Balerno, a western suburb of Edinburgh, serves as the practical gateway to this part of the Pentlands.
Reaching Bavelaw Castle requires a short walk, which suits the nature of the place well. From Balerno, walkers typically follow the Water of Leith path or drive to the car park at Harlaw, near the ranger centre, from which the castle is reachable in under a mile on foot by following the track along the reservoir shoreline. The terrain is largely flat on this approach and the path is well-maintained, making it accessible for most walkers including families with older children. There are no visitor facilities at the castle itself, which is privately owned, and access is to the exterior only. The best seasons to visit are late spring and autumn, when the light is low and golden and the surrounding vegetation adds colour without obscuring the views, though the area is walked year-round. Winter visits after snowfall transform the landscape dramatically and give the ruin a particularly evocative character against white hillsides.
One of the more intriguing aspects of Bavelaw's story is its connection to the broader tradition of Pentland Hill folklore and history. The hills above have associations with Covenanting struggles of the seventeenth century, and the landscape would have witnessed the movement of soldiers, refugees, and persecuted Presbyterians across its moorland tracks during that turbulent era. The castle itself was likely a witness to those times, standing as it does at a key crossing point between the lowland communities and the upland paths used to evade government forces. This layering of natural beauty, architectural antiquity, and historical weight makes Bavelaw Castle more than the sum of its crumbling walls — it is a place where the physical and historical landscape of Scotland converge in a way that rewards quiet, unhurried exploration.
