Storm Éowyn has caused serious damage to the looped boardwalks and interpretive signage on the site of the Marconi Station near Clifden, Co Galway.
A field inspection of the heritage trail at Derrygimlagh has revealed the full extent of the destruction and the site will be closed for a number of weeks at least.
The Marconi Heritage site covers around 300 acres of lakes and bogs.
Access to the site is provided by a 5km walking trail with elements of the old Marconi railway line, bog trackways and purpose-built wooden boardwalks.
The site includes the power station and transmission building as well as providing an impressive view of the world famous Roundstone Bog.
The original Marconi Station opened in 1907, allowing long distance communication with ships at sea and direct radio contact with North America.
It was the first operational "duplex" long distance radio station, allowing simultaneous two-way communications.
Jack Philips was the radio operator on the Titanic and trained at Derrygimlagh before taking his next and final job on the doomed ocean liner.
The Marconi Station is the famed landing spot of the first non-stop trans-Atlantic flight by Alcock and Brown who landed in the adjoining bog to signal their arrival on the European side of the Atlantic Ocean.
It was put out of action during the Irish Civil War.
Due to the extent of the damage, the site is closed to visitors until repairs can be carried out as some portions of the trail are now in a dangerous condition.
