How to Identify a Folly: A 10-Point Checklist for Historic Buildings
You are halfway along a footpath when the field stops making sense. At the top of a rise stands a stone tower with no door and no floor. Or a stretch of castellated wall with a Gothic arch that leads nowhere. Buildings like this invite the same question: is it a folly, a ruin, a farm building, or something else altogether?
Folly is a loose word. In everyday use it covers anything eccentric. In architectural history it usually means a building with no serious practical purpose, put up to please the eye, make a point or improve a view. The line is blurrier than most guidebooks admit, and plenty of buildings sit awkwardly between categories.
The checklist below is what to work through on site. No single answer is conclusive. Three or four together usually settle it.
The Ten-Point Checklist
- Does it do a job? Icehouses, dovecotes, game larders, estate cottages and water towers all worked for a living. So did windmills, smithies, brewhouses and small lodges. If the building could plausibly have earned its keep, suspect a working building first, however peculiar it looks. Look for wear marks, soot, chutes, hatches or storage spaces before you reach for the word folly.
- Does it belong to a designed landscape? Look for a ha-ha, an avenue of limes, a clump of trees on a ridge, an artificial lake, a drive that curves for effect. Follies rarely stand alone; they were placed. They are incidents in a route, meant to be glimpsed, approached and then left behind.
- Would it be seen from the house? Stand where the principal rooms faced. Eyecatchers were sited to be admired from drawing-room windows, terraces and carriage drives, not from the public road. If the best view of the building is from a back lane, that is a useful clue that it may have had another purpose.
- Is the scale wrong? A tower three metres square and eighteen metres high. Ceilings under two metres. Rooms with no means of heating. Comfort was never the brief. A folly may be dramatic, cramped or impossible to furnish, and often all three at once.
- Are the details applied rather than structural? Battlements on a plain brick box, buttresses carrying nothing, columns too slender for their load, mouldings cut in cheap material. Borrowed castle and abbey decoration, worn for effect. The ornament is a costume, not a skeleton.
- Are there blind windows and dummy features? A recess blocked before it was ever glazed, a chimney stack with no flue, a doorway filled with rubble. Once you start looking, these are the loudest tell-tales of all. They show that the appearance mattered more than the use.
- Is the ruin too well behaved? Real ruins lean, sag and collapse in one direction. Sham ruins keep crisp edges and neat coursing, and their mortar rarely matches a genuine fall of stone. A sham ruin is often a stable core with a picturesque skin of decay applied to it.
- Does the plan work as a building? No stair, no joists, no hearth, no window that opens. If you could not live or work in it as built, it was built for something else. Ask where the floor would have been, how anyone reached the upper level, and whether smoke could have escaped.
- Does the date fit the fashion? Most British follies belong to the eighteenth and early nineteenth centuries, when improvers reshaped estates and gentlemen came home from the Grand Tour full of temples and ruins. There are older and much later examples, so treat the date as a clue rather than a rule.
- What do the records say? A single estate plan or first edition Ordnance Survey sheet can settle in five minutes what an hour of guessing will not. Check before you commit to the label. Estate accounts, sale particulars and county histories often name the building and its purpose outright.
Purpose: the first and hardest test
"No practical purpose" is doing a lot of work in the definition. A prospect tower has a purpose: it gives you a view. A banqueting house has one: a private dinner away from the family. A summerhouse keeps the rain off. All three can still be follies, because the purpose is pleasure or display rather than profit. The question is not whether the building is used, but whether anyone ever needed it.
“Folly” is often a verdict passed by people who cannot see the original purpose. Use it as a last resort, not a first impression.
The useful building in fancy dress
Plenty of ordinary working buildings were dressed up in architectural clothes. A dovecote might acquire Gothic windows. A water tower could be given a castle-like crown. A dairy, a boat-house or a gamekeeper’s cottage might be tricked out with verandahs, bargeboards and rustic columns. These are not usually follies, because they still have a job to do. They are estate buildings in picturesque costume.
The distinction matters because it changes how you read the structure. If you can find the function, call it a picturesque farm building or an ornamental estate building. If the function has vanished entirely and only the display remains, then folly becomes the better fit. The costume has swallowed the body.
When Not to Call It a Folly
The word is seductive, and it is easy to apply too quickly. Before you settle on it, rule out the nearest alternatives:
- A genuine ruin: Real ruins have archaeology, fallen stone, occupation layers and a documented earlier life. They may be picturesque, but they were not built to be ruined.
- A garden building: Pavilions, gazebos and summerhouses were meant to be used. They often have seats, floors and roofs. They become follies only when use is impossible or clearly secondary to display.
- A working building in disguise: Dovecotes, icehouses, water towers and estate cottages can look eccentric while remaining practical. Function is the deciding factor.
- A later eccentric structure: Some towers, grottoes and shell houses were built in the nineteenth or twentieth centuries for private amusement. They may be follies, but they do not fit the classic Georgian estate pattern.
Recording What You Find
If you think you have found a folly, record it as carefully as you would any historic building. The evidence is often fragile, and the label can do harm if it stops further enquiry.
- Note the grid reference and orientation. The direction the building faces is part of the design.
- Photograph every elevation. Include details of windows, doors, battlements and any dummy features.
- Sketch a rough plan. Mark where floors, stairs or hearths might have been.
- Record materials and condition. Brick, stone, render, flint and cob all tell different stories.
- Check maps and estate records. A single early map can turn a guess into a fact.
In the end, the best test is a simple one: does the building make sense as a building, or only as a picture? If it exists to be looked at, to frame a view or to make a point, then you are probably standing in front of a folly. If it once kept ice, housed pigeons, stored water or sheltered a worker, call it something else and enjoy it just as much.
