Kids were off school so we took a day to go and see a few things we had spotted whilst out and about. In particular, on top of this hill we could see what looked like a metal pyramid. Found more about it on the internet, and it’s known as the Tetraeder, and is made of steel pipes built on a former mining heap. It’s around 50 metres tall, and you can walk to the top of it, great views from there and a decent walk to the top of the hill too. And free, what could be better.
