The base of the observatory in on wheels and runs in a rail set in concrete so the whole observatory rotates.

The top section was what I was interested in. With that section on the ground, it was exactly the right height to house a telescope. At 14' diametre a good size too.
I had thoughts of getting a second hand one & mounting it on a track, but never did.

Plenty of those around here but all in use. No second-hand ones. I keep an eye out at the tip though where they chuck their useless water tanks (full of rust holes).
