Before the brightly-coloured, plastic playground equipment sitting safely on softfall and securely enclosed by a fence that we find in today's parks ¨C there were the playgrounds of the '50s, '60s, '70s and '80s.
Metal bars, dangerous equipment, hard concrete surfaces and lots of scabbed knees!
And let's not forget the summer time burns that were a rite of passage thanks to those long metal slides that turned to fire on a hot day.
Let's take a look back at some of the playground equipment we grew up with.

Let's hear it for the old-school metal merry-go-rounds.
If you and your friends spun on this too fast, a head injury or grazed elbow was guaranteed!
When shared to Twitter, this photo clearly triggered many adults.
"Most dangerous play equipment in the playground as a kid," said one. "Especially if there were older kids pushing it. I'm sure we all went flying at one time or another."
"Trying to get off it was a feat in itself without getting hurt," commented another.
The traditional jungle gym (or climbing frame) was invented in 1920 and was made from, you guessed it, metal.
And, even as the decades passed, there was no impact-absorbing surface to fall onto like in today's modern parks, just hard concrete or bark chips.
Needless to say, kids often injured themselves bumping their heads on the metal bars or falling from the frame.
Running and gliding in circles on a maypole is a staple memory for any kid who played in a retro playground.
Ah, so simple and yet so many hours of entertainment from two slabs of wood and a metal pole.
Not to mention splinters.
See-saw or monkey bars?
Parents and kids enjoy a newly-redesigned playground in a city park in D¨¹sseldorf, Germany in 1968.
Colourful animal-themed equipment was plentiful in old playgrounds much like this cute rocking horse.
Before playground slides became shorter, safer and made from plastic, they used to be towering metal constructions that left nervous parents shaking at the bottom.
Not only did they rust and burn your skin on hot days, but slippery dips were sometimes so tall and open that climbing to the top was a feat - and a hazard ¨C in itself.
Another case in point ¨C this dangerous-looking slide and climbing frame from a park in Milan, Italy in 1957.
Metal jungle gyms were common but you were especially lucky if you had one in the shape of a dome.
While these jungle gyms were fun, the metal bars made them burn our feet and hands on those hot summer days!
Rocket ship-themed equipment was a playground staple that is increasingly rare in playgrounds today.
While 'Witches Hats' were once a key feature, they have been phased out and banned from playgrounds since the 1980s due to safety concerns.
"Witches hats were terrifying!" said one Twitter user.
"Popular with older teenagers who would deliberately try to shake you off onto the concrete."
