Scandinavian moon craters, whales, and sunken ships.
One of the disappointments of playparks in Edinburgh is how similar they sometimes are. I was excited recently when I discovered the existence of a Danish company called Monstrum. Their designs of playparks include ships sunk into the grounds, whales you can crawl into, giant spiders...
I recommend looking at all the pretty pictures on their website (visiting might be fun too- if anyone has been please let me know)
"Why only play on a monkey frame and a sandbox, when you can play in a moon crater or a submarine or a giant spider or an enormous snail or a Trojans horse or a rocket or an ant or a princess castle?" - Monstrum
I hope something like this comes to Edinburgh soon.
