The UK's National Trust says the "safety of visitors and staff is of utmost importance"
Police in the North are investigating damage to the Carrick-a-Rede rope bridge in Co Antrim.
The popular tourist attraction has been closed to visitors after it was damaged by vandals overnight.
The bridge - first erected in 1755 by salmon fishermen, and replaced several times in recent decades - will be closed for the forseeable future, according to the National Trust.
In a brief statement, officials said: "The safety of visitors and staff is of utmost importance and we are currently assessing the level of damage."
Hundreds of thousands of visitors cross the bridge every year, and it is only a short drive from the Giant's Causeway.
The closure comes ahead of the June bank holiday weekend, and amid the busy summer tourist season
