The Ingenious Reason Medieval Castle Staircases Were Built Clockwise

If you’re a fan of Game of Thrones or medieval programs in general, you’re probably familiar with action-packed battle scenes during which soldiers storm castles, dodge arrows, and dash up spiral staircases. And, while those spiral staircases might not necessarily ascend clockwise in every television show or movie you’ve watched, they usually did in real life.

According to Nerdist, medieval architects built staircases to wrap around in a clockwise direction in order to disadvantage any enemies who might climb them. Since most soldiers wielded swords in their right hands, this meant that their swings would be inhibited by the inner wall, and they’d have to round each curve before striking—fully exposing themselves in the process.

Just as the clockwise spiral hindered attackers, so, too, did it favor the castle’s defenders. As they descended, they could swing their swords in arcs that matched the curve of the outer wall, and use the inner wall as a partial shield. And, because the outer wall runs along the wider edge of the stairs, there was also more room for defenders to swing. So, if you’re planning on storming a medieval castle any time soon, you should try to recruit as many left-handed soldiers as possible. And if you’re defending one, it’s best to station your lefties on crossbow duty and leave the tower-defending to the righties.

On his blog All Things Medieval, Will Kalif explains that the individual stairs themselves provided another useful advantage to protectors of the realm. Because the individual steps weren’t all designed with the same specifications, it made for much more uneven staircases than what we see today. This wouldn’t impede the defenders, having grown accustomed to the inconsistencies of the staircases in their home castle, but it could definitely trip up the attackers. Plus, going down a set of stairs is always less labor-intensive than going up.

Staircase construction and battle tactics are far from the only things that have changed since the Middle Ages. Back then, people even walked differently than we do—find out how (and why) here.

By this point, your eco-friendly pal probably has a reusable water bottle that accompanies them everywhere and some sturdy grocery totes that keep their plastic-bag count below par. Here are 10 other sustainable gift ideas that’ll help them in their conservation efforts.

1. Reusable Produce Bags; $13

No more staticky plastic bags.Naturally Sensible/Amazon

The complimentary plastic produce bags in grocery stores aren’t great, but neither is having all your spherical fruits and vegetables roll pell-mell down the checkout conveyor belt. Enter the perfect alternative: mesh bags that are nylon, lightweight, and even machine-washable.

Buy it: Amazon

2. Animal Tea Infusers; $16

Nothing like afternoon tea with your tiny animal friends.DecorChic/Amazon

Saying goodbye to disposable tea bags calls for a quality tea diffuser, and there’s really no reason why it shouldn’t be shaped like an adorable animal. This “ParTEA Pack” includes a hippo, platypus, otter, cat, and owl, which can all hang over the edge of a glass or mug. (In other words, you won’t have to fish them out with your fingers or dirty a spoon when your loose leaf is done steeping.)

Buy it: Amazon

3. Rocketbook Smart Notebook; $25

Typing your notes on a tablet or laptop might save trees, but it doesn’t quite capture the feeling of writing on paper with a regular pen. The Rocketbook, on the other hand, does. After you’re finished filling a page with sketches, musings, or whatever else, you scan it into the Rocketbook app with your smartphone, wipe it clean with the microfiber cloth, and start again. This one also comes with a compatible pen, but any PILOT FriXion pens will do.

Buy it: Amazon

4. Food Huggers; $13

It’s hard to compete with the convenience of plastic wrap or tin foil when it comes to covering the exposed end of a piece of produce or an open tin can—and keeping those leftovers in food storage containers can take up valuable space in the fridge. This set of five silicone Food Huggers stretch to fit over a wide range of circular goods, from a lidless jar to half a lemon.

Buy it: Amazon

5. Swiffer Mop Pads; $15

Swiffers may be much less unwieldy than regular mops, but the disposable pads present a problem to anyone who likes to keep their trash output to a minimum. These machine-washable pads fasten to the bottom of any Swiffer WetJet, and the thick microfiber will trap dirt and dust instead of pushing it into corners. Each pad lasts for at least 100 uses, so you’d be saving your eco-friendly friend quite a bit of money, too.

Buy it: Amazon

6. SodaStream for Sparkling Water; $69

A fondness for fizzy over flat water doesn’t have to mean buying it bottled. Not only does the SodaStream let you make seltzer at home, but it’s also small enough that it won’t take up too much precious counter space. SodaStream also sells flavor drops to give your home-brewed beverage even more flair—this pack from Amazon ($25) includes mango, orange, raspberry, lemon, and lime.

Buy it: Amazon

7. Washable Lint Roller; $13

There’s a good chance that anyone with a pet (or just an intense dislike for lint) has lint-rolled their way through countless sticky sheets. iLifeTech’s reusable roller boasts “the power of glue,” which doesn’t wear off even after you’ve washed it. Each one also comes with a 3-inch travel-sized version, so you can stay fuzz-free on the go.

Buy it: Amazon

8. Countertop Compost Bin; $23

Like a tiny Tin Man for your table.Epica/Amazon

Even if you keep a compost pile in your own backyard, it doesn’t make sense to dash outside every time you need to dump a food scrap. A countertop compost bin can come in handy, especially if it kills odors and blends in with your decor. This 1.3-gallon pail does both. It’s made of stainless steel—which matches just about everything—and contains an activated-charcoal filter that prevents rancid peels and juices from stinking up your kitchen.

Buy it: Amazon

9. Fabric-Softening Dryer Balls; $17

Also great for learning how to juggle without breaking anything.Smart Sheep

Nobody likes starchy, scratchy clothes, but some people might like blowing through bottles of fabric softener and boxes of dryer sheets even less. Smart Sheep is here to offer a solution: wool dryer balls. Not only do they last for more than 1000 loads, they also dry your laundry faster. And since they don’t contain any chemicals, fragrances, or synthetic materials, they’re a doubly great option for people with allergies and/or sensitive skin.

Buy it: Amazon

10. Rechargeable Batteries; $40

Say goodbye to loose batteries in your junk drawer.eneloop/Amazon

While plenty of devices are rechargeable themselves, others still require batteries to buzz, whir, and change the TV channel—so it’s good to have some rechargeable batteries on hand. In addition to AA batteries, AAA batteries, and a charger, this case from Panasonic comes with tiny canisters that function as C and D batteries when you slip the smaller batteries into them.

The glamorous life of a royal comes with a strict set of fashion rules. Exposed shoulders are frowned upon at weddings, and travel wardrobes must always include one all-black outfit. But not every fashion custom comes from established tradition. As Reader's Digest reports, Queen Elizabeth II's habit of wearing bright colors is self-imposed—but her flashy style is more than an aesthetic preference.

At public events, the Queen of England often arrives sporting neon shades, from lime green to robin's egg blue. Though her classy hats and jackets are typical for a royal, the playful colors they come in may seem like an unusual statement for the 94-year-old queen. Her daughter-in-law Sophie, Countess of Wessex, recently revealed that Her Majesty chooses the bold outfits, not for herself, but for the spectators who come to see her.

“She needs to stand out for people to be able to say ‘I saw the Queen’,” the Duchess said in the 2016 documentary The Queen at 90. Her public appearances can draw massive crowds, and by dressing in eye-catching shades, Queen Elizabeth ensures even people in the back will be able to spot her.

The vibrant look is unique to the Queen, but other fashion rules she follows are more universal to the rest of the women in the royal family. From hats to handbags, here are the reasons behind other elements of the royal dress code.
