I think I might be more-prone to nerd sniping when I’m travelling.
Last week, a coworker pointed out an unusually-large chimney on the back of a bus depot and I lost sleep poring over 50s photos of Dutch building sites to try to work out if it was
original.
When a boat tour guide told me that the Netherlands used to have a window tax, I fell down a rabbit hole of how it influenced local architecture and why the influence was different in the UK.
Why does travelling make me more-prone to nerd sniping? Maybe I should see if there’s any likely psychological effect that might cause that…
From 1696 until 1851 a “window tax” was imposed in England and Wales1.
Sort-of a precursor to property taxes like council tax today, it used an estimate of the value of a property as an indicator of the wealth of its occupants: counting the number of
windows provided the mechanism for assessment.
Window tax replaced an earlier hearth tax, following the ascension to the English throne of Mary II and William III of Orange. Hearth tax had come from a similar philosophy: that
you can approximate the wealth of a household by some aspect of their home, in this case the number of stoves and fireplaces they had.
(A particular problem with window tax as enacted is that its “stepping”, which was designed to weigh particularly heavily on the rich with their large houses, was that it similarly
weighed heavily on large multi-tenant buildings, whose landlord would pass on those disproportionate costs to their tenants!)
Why a window tax? There’s two ways to answer that:
A window tax – and a hearth tax, for that matter – can be assessed without the necessity of the taxpayer to disclose their income. Income tax, nowadays the most-significant form of
taxation in the UK, was long considered to be too much of an invasion upon personal privacy3.
But compared to a hearth tax, it can be validated from outside the property. Counting people in a property in an era before solid recordkeeping is hard. Counting hearths is
easier… so long as you can get inside the property. Counting windows is easier still and can be done completely from the outside!
One of the things I learned while on this trip was that the Netherlands, too, had a window tax for a time. But there’s an interesting difference.
The Dutch window tax was introduced during the French occupation, under Napoleon, in 1810 – already much later than its equivalent in England – and continued even after he was ousted
and well into the late 19th century. And that leads to a really interesting social side-effect.
Glass manufacturing technique evolved rapidly during the 19th century. At the start of the century, when England’s window tax law was in full swing, glass panes were typically made
using the crown glass process: a bauble of glass would be
spun until centrifugal force stretched it out into a wide disk, getting thinner towards its edge.
The very edge pieces of crown glass were cut into triangles for use in leaded glass, with any useless offcuts recycled; the next-innermost pieces were the thinnest and clearest, and
fetched the highest price for use as windows. By the time you reached the centre you had a thick, often-swirly piece of glass that couldn’t be sold for a high price: you still sometimes
find this kind among the leaded glass in particularly old pub windows5.
As the 19th century wore on, cylinder glass became the norm. This is produced by making an iron cylinder as a mould, blowing glass into it, and then carefully un-rolling the cylinder
while the glass is still viscous to form a reasonably-even and flat sheet. Compared to spun glass, this approach makes it possible to make larger window panes. Also: it scales
more-easily to industrialisation, reducing the cost of glass.
The Dutch window tax survived into the era of large plate glass, and this lead to an interesting phenomenon: rather than have lots of windows, which would be expensive,
late-19th century buildings were constructed with windows that were as large as possible to maximise the ratio of the amount of light they let in to the amount of tax for which
they were liable6.
That’s an architectural trend you can still see in Amsterdam (and elsewhere in Holland) today. Even where buildings are renovated or newly-constructed, they tend – or are required by
preservation orders – to mirror the buildings they neighbour, which influences architectural decisions.
It’s really interesting to see the different architectural choices produced in two different cities as a side-effect of fundamentally the same economic choice, resulting from slightly
different starting conditions in each (a half-century gap and a land shortage in one). While Britain got fewer windows, the Netherlands got bigger windows, and you can still see the
effects today.
…and social status
But there’s another interesting this about this relatively-recent window tax, and that’s about how people broadcast their social status.
In some of the traditionally-wealthiest parts of Amsterdam, you’ll find houses with more windows than you’d expect. In the photo above, notice:
How the window density of the central white building is about twice that of the similar-width building on the left,
That a mostly-decorative window has been installed above the front door, adorned with a decorative
leaded glass pattern, and
At the bottom of the building, below the front door (up the stairs), that a full set of windows has been provided even for the below-ground servants quarters!
When it was first constructed, this building may have been considered especially ostentatious. Its original owners deliberately requested that it be built in a way that would attract a
higher tax bill than would generally have been considered necessary in the city, at the time. The house stood out as a status symbol, like shiny jewellery, fashionable clothes,
or a classy car might today.
How did we go wrong? A century and a bit ago the super-wealthy used to demonstrate their status by showing off how much tax they can pay. Nowadays, they generally seem
more-preoccupied with getting away with paying as little as possible, or none8.
Can we bring back 19th-century Dutch social status telegraphing, please?9
Footnotes
1 Following the Treaty of Union the window tax was also applied in Scotland, but
Scotland’s a whole other legal beast that I’m going to quietly ignore for now because it doesn’t really have any bearing on this story.
2 The second-hardest thing about retrospectively graphing the cost of window tax is
finding a reliable source for the rates. I used an archived copy of a guru site about Wolverhampton history.
3 Even relatively-recently, the argument that income tax might be repealed as incompatible
with British values shows up in political debate. Towards the end of the 19th century, Prime Ministers Disraeli and Gladstone could be relied upon to agree with one another on almost
nothing, but both men spoke at length about their desire to abolish income tax, even setting out plans to phase it out… before having to cancel those plans when some
financial emergency showed up. Turns out it’s hard to get rid of.
4 There are, of course, other potential reasons for bricked-up windows – even aesthetic ones – but a bit of a giveaway is if the bricking-up
reduces the number of original windows to 6, 9, 14 or 19, which are thesholds at which the savings gained by bricking-up are the greatest.
5 You’ve probably heard about how glass remains partially-liquid forever and how this
explains why old windows are often thicker at the bottom. You’ve probably also already had it explained to you that this is complete bullshit. I only
mention it here to preempt any discussion in the comments.
6 This is even more-pronounced in cities like Amsterdam where a width/frontage tax forced
buildings to be as tall and narrow and as close to their neighbours as possible, further limiting opportunities for access to natural light.
7 Yet I’m willing to learn a surprising amount about Dutch tax law of the 19th century. Go
figure.
An easy find. Didn’t take nor leave any books, but briefly skimmed the Borland JBuilder 2 Getting Started guide, because it was familiar/nostalgic. Pretty sure I used this tool… about
25 years ago!
An easy find. As a approached I thought that a couple cuddling here might be in my way, but they were just getting ready to leave as I arrived! SL (love
the long thin logbook!), TFTC. Now to make my way back to the station!
Eww. Had to put my hand into two gross holes before finding the (correct) third gross hole I needed to put my hand into. Worth it in the end for a happy smiley face. Thanks for bringing
me to this place and teaching me its history. TFTC!
TFTC! I’m not carrying any tickets for UK transport, but I’ve got a (mildly
defaced) British banknote and I found a tram (the number 13, which connected me to my hotel this week) and a ferry (which I then went and caught to go find some more caches!).
Cash? Not carrying much of that. But my credit card sits at the front of my minimalist wallet and, as a bonus, shows my geocaching username (which is the same as my actual name) without
showing the actual card number. TFTC!
No luck here despite an extended search, the hint, and the spoiler image. Confident I’ve found the right host but no sign in the cache. I wonder if another geocacher is holding it right
now, sitting somewhere nearby to sign the log? Or else it’s probably gone missing. 😢
Love the monument, delighted to see it. Took me a long, long time to find the cache though! Started by looking near the coordinates but couldn’t find anything likely to host the cache.
Spotted a likely host by the waterside and, evert though the coordinates seemed off, gave a good search there before giving up.
Then went to a nearby stall to buy a souvenir of my trip when I realised another possible route to the coordinates. Turns out there’s a big van parked right now blocking access to the
cache! (Looks like they’re setting up for an event, maybe for King’s Day?) Squeezed past and used my phone in selfie mode as a mirror to scan the place I thought the cache might be.
Success! Retrieved cache, signed log, and returned.
Thanks for bringing me here, and for a well-hidden cache. Greetings from Oxfordshire, UK!
After a lot of walking so far this morning I was glad of the opportunity to stop and take a rest nearby while I signed the log. TFTC, and
greetings from Oxfordshire, UK.
Hiding place is a bit damp and grimy but a bit of digging through leaf litter soon revealed the cache. The nearby climbing frame is epic: my kids would love it! Greetings from
Oxfordshire, UK. TFTC.
Amazing geocache, FP awarded! I’ve been visiting Amsterdam for the last few days to meet up with work colleagues from around the world, but this
morning I’m having a bit of an explore/geocaching expedition before I catch a train back to the UK. TNLN, SL, TFTC!
