There was plenty of outrage earlier this calendar month when aLondon storefront revealed pavement spikesmeant to keep the homeless from get too cozy . While these shiny sticker did seem specially Temple of Doom - ish , they were n’t all that strange : There are plenty of piddling details design into our city that recount us what to do , where to go , and give us hints of what came before .
While the intentions of some details , like sidewalk spikes , are inherently obvious , not all these civic designs are always so blunt . Some infrastructural elements have to be purposely disguised , so we , the world , will not mess with them . Others seek to prod us towards a certain behavioural pattern using not - so - pernicious hints that purportedly wo n’t ruin a spot ’s overall esthetic . And other features are simply artifacts of a unlike prison term and position , which have not yet managed to be wipe out .
Here are some infrastructural cue you might have seen on your local street , and what they ’re trying to recount you .
Don’t Sleep Here

The London spikes in question wereactually removedafter an online petition went viral , but there are plenty of other completely accepted ways that cities foreclose sleep in public spaces . You ’ve definitely discover the creative fences and cosmetic railing that telephone windows and ledges with welcoming studs and teeth . The example above is in Manhattan .

Even on busbar terrace , which are suppose to be comfortable , those petty humps mid - bench are there to ensure you do n’t get too comfortable . bench are also advisedly design from slippy materials or with a steep incline so one has to work to rest upright . courteous , huh ?
Utility Lines Below

Those too - orderly graffiti tags scatter across the street and sidewalk are actually very specific markings from public works departments and public utility company companies . Anexcellent explainerover at Smithsonian Magazine tells the story of these civic hieroglyphics : the system , which is called DigAlert , was created by American Public Works Association after construction doer accidentally bring down through a petroleum grapevine in 1976 , do a black plosion .
There ’s even a ready to hand chart to aid learn which colors translate to which utility program lines . In increase to the colors , the rules dictate that certain lines , arrows and shapes are used to show how the utility are moving through the ground .
No Skating

Perhaps the most famous ( or ill-famed ) infrastructural modifications in cities are the dash and notches apply to rail and benches to prevent skaters from drudge down the face of them .

Some are just ugly , but others , like these polo-neck , which just bechance to be creep along the top of this workbench , are quite creative . Photographer Marc Vallée has beenbeautifully documentingsome of the worst wrongdoer in the UK and beyond .
This Sidewalk Is Old

pavement maintenance is the bane of many metropolis ’ existence — with ten of thousand of miles to monitor , it ’s no marvel many public works departments raise out the line of work to individual companies . So many cities began requiring private contractor to stamp their study with their name and date as a style to check tone but also keep tabs on which sidewalk needed to be repaired or replaced .

Toronto has an especially interesting — and artful — compendium of pavement stampsthat date stamp back to the early 20th century , and other cities have both contractor and inspector postage . The exercise is still used currently in many metropolis , so 100 class from now people might be admiring the geezerhood of a 2014 pestle . Or will we even have sidewalks then ?

Along the same lines as the anti - sleeping spikes , these thin spiny spokes in high-pitched - up berth are intend to discourage larger birds from roost — which help to prevent nests from spring , yes , but also serve nearby human residents avoid racket and lots of cocksucker below .

Found all over the world in different variable quantity — in Denmark they go by the adorable name of fuglepigge — the spike are construe as humane because they but encourage birds to land elsewhere . They ’re just not in particular attractive .

walk in older neighborhoods you might notice tiny shabu roofing tile embedded in the sidewalk around the incoming to buildings . These are called “ vault light ” or “ deadlights ” and they were used to swamp the basements of honest-to-goodness building with natural light source before the daytime of electricity .

Untapped Cities has anice storyabout the chronicle of these “ empty pavement ” in New York City . Many have been fill up in due to the danger they present ( they have been sleep together to cave in ) but you may still findplenty of examplesthroughout the city .
Don’t Jump

Anti - suicide barrier are becoming more and more usual on popular memorial as they have been proven to deter citizenry from jumping off bridges and other marvellous structures .

Most of the new barrier are a case of profits made from thick cables , interchangeable to the oneproposed for the Golden Gate Bridge . These are pop because unlike a marvellous railing or fence , they do n’t interpose with view .
Horses Used to Be Tethered Here

You ’ll have to look very cautiously for these tiny rings bolted to the sidewalk in older urban area . These are sawhorse rings , back from the twenty-four hours when people needed a place to tie up their horses and sawbuck - drawn coach . Think of these as pre - car parking spaces .

Many cities have pulled out the ring as part of standard sidewalk upgrade . In Portland , artists began tetheringtoy horses to the ringsto convey care to them .
Oil Is Below

In many cities the encroachment of urbanisation has not stifled the fact that plentiful oil must be extracted from the earth . In many places where oil production was high , the streets used to be covered in derricks hop-skip to suck in the black gold from below . Oklahoma City , domicile of one of the largest petroleum backlog in the world , has a derrick decent there in the front yard of the capitol .
Still from Oil of L.A.
Other cities work to mask the derricks as decorative buildings or structures . Oil of L.A.is a lovely documentary that chase the gonzo structures around Los Angeles used to hide oil derrick , like one on the campus of Beverly Hills High School .
The Cold War Was Here

Air maraud siren ( formally known as civil defense lawyers sirens ) left over from both World War II and the Cold War are still notice in many city around the humanity . These alert systems were build to warn occupier in the event of an imminent bombardment and , later , a atomic attack .

While some have been repurposed as crack or tsunami sirens — and in other piazza , the sirens are still woefully used as warning for missile or other attacks — many of the stations have fallen into disrepair over the age .
