Robinswood Hill dates back to the Jurassic period - that’s over 200 million years ago - and would have been under the sea.
The Jurassic period is famous for ammonites and belemnites, these were squid-like animals that lived in the sea. Look through the binoculars and pretend that you are standing on the seabed - can you imagine what you might have seen back then? There would have been no city, trees or grass. Instead, you would be surrounded by warm water.
Maybe some ammonites would be floating above your head. These were creatures with shells that could grow up to two meters in size - about as big as a king size bed.

Perhaps some belemnites swim by, with their long, bullet-shaped shells.
Over millions of years the sea changed a lot, and at times, the area you are looking at would have been a dry seabed. The ups and downs in sea level led to a build up of sediment on the sea floor, and as animals like ammonites died, their bodies were buried in this. If the conditions were right, and the area was left undisturbed for millions of years, these formed into fossils.
Robinswood Hill is full of fossils, and is a protected area known as a Site of Special Scientific Interest (SSSI) for its geology. If you visit the quarry you might even find a fossil yourself - but please look and don't collect, so they are left for others to see too.
Take another look through the binoculars, what do you see in the present day? Are there any birds in the trees, butterflies flying by or dogs running through the park? A lot has changed in 200 million years.
