The Story of Scottish Tower Houses Explained

What Makes a Tower House a Tower House

Travel through the Scottish Highlands, the Borders or the north-east and you will meet them everywhere: stout, harled rectangles of stone, often four or five storeys high, with crow-stepped gables, a parapet and a single round turret clinging to one corner. These are tower houses, and they are the most distinctive domestic buildings Scotland ever produced.

The great age of the tower house ran roughly from the fourteenth to the early seventeenth century. In a country where central authority was thin on the ground, a laird built upwards for two reasons at once. Height gave him warning of approaching trouble, and it gave him status. A tower was a statement as much as a stronghold — the family name carved above the door, the coat of arms on the panel, the sheer bulk of the thing announcing that here lived someone of consequence.

Most towers follow a simple plan. A rectangular block of three to five storeys, walls commonly a metre or more thick at the base and tapering slightly as they rise, with a vaulted cellar at ground level and a parapet walk at the top. Variations mattered: the L-plan, with a wing projecting from one corner to protect the entrance, and the Z-plan, with towers at diagonally opposite corners, both gave defenders flanking fire along the walls. By the 1600s, as peace settled, the defensive grammar loosened and towers grew into grander, more comfortable houses.

Thick Walls, Iron Yetts and Shot Holes

The defensive kit of a Scottish tower house was practical rather than theatrical. There were rarely moats and seldom drawbridges; instead the design relied on making the ground floor almost impossible to take.

• The entrance was usually at first-floor level, reached by a removable timber stair or from within the barmkin wall. Break the stair and the door was out of reach.
• The iron yett — a heavy grid of crossed bars, hinged behind the timber door — was standard. Even if the door was burned or battered, the yett held.
• Shot holes, simple vertical slits or keyhole shapes, were set into the walls to give a defender a narrow field of fire without offering a target.
• Corbelling and machicolations at the wall head let defenders drop stones or pour unpleasant things onto anyone at the base.
• The parapet and caphouse on the roof gave a lookout point and a last defensible position.

Ground floors were usually vaulted in stone and used for stores, brewhouse or livestock in a raid. Living space sat above, where the walls could be thinner, the windows larger and the fireplaces generous.

The Turnpike Stair and the Anatomy of the Interior

Nothing is more characteristic of the tower house than the turnpike stair — a tight spiral of stone steps, often winding within a turret corbelled out from the main wall. It saved floor space, needed no landing, and could be defended by one person at the top.

The familiar story is that turnpikes wind clockwise as you climb, so that a right-handed defender retreating upwards had his sword arm free while the attacker below was cramped against the newel. It is a fine theory, and you will hear it in every guidebook. Treat it with a pinch of salt: many Scottish turnpikes wind the other way entirely, and the design was probably driven as much by the lie of the building as by swordplay.

Elsewhere in the interior, look for the hall on the first or second floor, the largest room and the heart of the household; the laird's lug, a small concealed niche behind the fireplace or in a wall, allowing the master to overhear conversations in the room below; the garderobe, a projecting turret with a chute discharging down the outside wall; and the painted ceilings and panelling that survive in the grander examples of the later period.

The Barmkin, Walled Gardens and the Wider Estate

A tower on its own was never the whole picture. Around the base ran the barmkin, a walled enclosure that sheltered outbuildings, cattle, horses and the household's stores during a raid. Get inside the barmkin and you had a fighting chance; lose the cattle and you had lost the year's wealth.

As the sixteenth century gave way to the seventeenth, the barmkin gave way to the walled garden. This is the quiet glory of many Scottish tower houses. High stone walls did double duty: they kept out deer and rabbits, and they stored heat, creating a microclimate several degrees kinder than the surrounding hillside. Along south-facing walls you will find espaliered apples and pears, plum and cherry trees, soft fruit, and the herbs and pot-herbs that kept a kitchen going through a Highland winter. Look for the potting shed, the sundial, the bee boles, and the gap in the wall — often called the garden door — that framed the view the designer wanted you to see.

Towers Today: Family Homes, Hotels and Ruins

Remarkably, most surviving tower houses are not museums. Some are still lived in by the families whose ancestors built them, adapted over the centuries with sash windows, central heating and electricity — though often with the turnpike stair retained as a slightly alarming route to bed. Others have been converted into small hotels and self-catering retreats, where you can sleep in a vaulted chamber and eat breakfast in the old hall.

Others again are ruins: a fragment of gable, a chimney stack standing clear of the walls, a stair rising into open sky. These are often the most atmospheric, and the most fun to explore, precisely because you have to reconstruct the building in your head.

Planning Your Own Tower-House Trail

• Go in the shoulder seasons. Late April to June and September to October give reasonable light, quieter roads and far fewer midges than high summer.
• Check opening arrangements. Many towers are private homes, open on limited days or by appointment only. Never assume a gate means a welcome.
• Look up as well as around. Parapets, corbels, crow-steps, water spouts and carved armorial panels are all above eye level.
• Bring a torch. Vaulted cellars and turnpike stairs are genuinely dark, whatever the weather outside.
• Allow time for the garden. The walled garden is usually the reason the tower was sited where it was.
• Drive the single-track roads patiently. Passing places are for passing, and the journey between towers is half the pleasure.

Read the building from the ground up: defended base, comfortable middle, proud parapet, sheltered garden. Once you can see that pattern, every tower house in the Highlands becomes legible — and considerably harder to drive past without stopping.
