1903-2017. Bidston Observatory, built in 1866 when Liverpool observatory was forced to relocate due to the industrial expansion of the city. It became of huge important during the second World War when it predicted the tidal patterns for D-day, and the telescopes housed in the observatory were previously used to watch planetary bodies in order to calculate the exact time needed for nautical navigation, and was transferred to ships in the docks by the firing of the one o’clock gun. After almost 14 decades of pioneering astronomy the observatory was left unused and served as a derelict monument ontop of the hill for more than ten years. Luckily the building was saved and is currently under ownership with aims of becoming a fully functional dwelling.
