The print shows the Edinburgh City Observatory during its twilight hours. The heavy clouds in the sky create dramatic effects for the setting. The shadows extending from the neglected lawn appear soft but create an eerie atmosphere.

The picture maintains a peaceful atmosphere while showing a moment that has frozen in time. The location appears to stand between two time periods as it showcases ancient scientific findings beneath boundless celestial space.
