The half-mile Gobbins Coastal Path was designed by Berkley Dean Wise for the Belfast and Northern Counties Railway Company, and during its heyday, was more popular than Giant's Causeway. Its 15 spectacular metal bridges and path carved into the cliff helped attract visitors seeking stunning views of the coast.
However, the path fell into disrepair after the Second World War and closed in 1954.
In 2011, plans to restore the path were announced. Many of the original metalwork structures and rails had collapsed or been damaged by rust and the action of the sea.
The contractors, McLaughlin & Harvey, were involved in the restoration of the path, valued at £6m. It included 1km of coastal path, hand railings and 15 bridge structures.
One of the biggest achievements of the project was the installation of a five-tonne tube bridge, which was lowered on to the path near Larne. A drone camera was used to capture stunning footage of this amazing engineering achievement.
