Despite regularly driving past I had failed to notice this in the last 12 years until I finally spotted this stone circle in a park.

On closer investigation the slate monoliths mark the hours on a sundial.

You stand on the appropriate footsteps for the time of year and then your shadow is cast towards the time.

Sadly despite only being just over 10 years old the area was covered in broken glass and the paths are getting overgrown.

There also some small mosaics of local scenes on the dial.
