"In 2020, two heavy, modern excavators took about a year to place 200 yards of rough boulders on top of a short section of the East Pier at Dún Laoghaire Harbour, Dublin. A very poor effort compared to two centuries ago, from 1820 to 1824, at which time they were able to largely construct 2 miles of billiard table-level piers, out to sea, and about 250 feet wide at the base.
This speculative video gives (possible) evidence for the use of ancient hidden technology in the construction of the monumental harbour. The technology would have been used to cut and physically manipulate and maneuver the rock."
