Walk On The Wildside...

Seeing as we’re talking man-made constructions, the Breakwater at Holyhead Harbour is one of the longest breakwaters in Europe, stretching over 1.8 miles out into the sea, protecting the harbour from the wilds of the Irish Sea. This isn’t a modern construction but dates back to around 1870 when they used timber scaffolding to help construct it.
It’s now in some state of disrepair and is being maintained by Stena Ferries at a cost of £150,000 a year just to prevent further decay. Once again, there’s lots of talk about restoring it and promoting it as a tourist attraction with a small gauge railway running along its length. It is possible to walk or even cycle along it, but not recommended when those Irish Sea storms come calling.
