Kings Dock - Liverpool England

The dock was designed by Henry Berry and opened in 1785.

Further docks were added and eventually all were interconnected by lock gates, extending 7.5 miles along the Liverpool bank of the River Mersey.

The interconnected dock system was the most advanced port system in the world. The docks entailed ship movements within the dock system 24 hours a day, isolated from the high River Mersey tides.
