A public inquiry may be held over plans to demolish Tenby's 100-year-old former lifeboat station.
A new modern building has opened nearby and the RNLI said it cannot afford the upkeep of both.
The RNLI applied to the Pembrokeshire Coast National Park Authority for planning permission to demolish the listed building.
The authority said it had been informed by the Welsh Assembly Government the application was being called in.
A spokesperson said: "This may mean that a public inquiry will be held, but at this time, we do not know either whether this will be the case or, if it is, when such an inquiry would be held."
The station's future had divided opinion.
Tenby Civic Society has backed the RNLI's application but the Ancient Monuments Society and Victorian Society both want the building retained.
