The action was taken by anti-lockdown and anti-face mask protesters.
Among those who spoke at the protest were Professor Dolores Cahill, Chairwoman of the Irish Freedom Party and former General Election candidate Ben Gilroy.
Speakers at the event addressed a large crowd, many of whom stood close together and did not wear masks.
The Irish Freedom Party said in a statement: "The sense of anger in the air is palpable. Government imposed restrictions have resulted in massive job losses, a mental health crisis, a debt crisis, a backlog in non Covid health related problems. Our inalienable rights have been trampled on."
