DUP Assemblyman Mervyn Storey said he was extremely disappointed that the centre on the outskirts of Dunloy had been permitted to be used for what he termed an "insensitive" display.
"No one should be surprised at republicans hijacking any venue following on from Casement Park," he said.
"The hunger strike commemorations are only being used as another weapon in what republicans would describe as 'the struggle'."
Mr Storey said organisers were "presenting the hunger strikers as heroes, champions of a just cause and people who should be venerated", where in fact they were "responsible for some of the most vile terrorist crimes".
"It is an insult to the victims in north Antrim that such an event should take place and displays great insensitivity.
"It proves yet again that despite all the words from republicans, they believe that what the IRA was engaged in was right and should be remembered in this way," he said.
