I do not know if this was an official state sponsored event rather than a commercial event.
In the past the park had been made available by Dublin City Council for events - such as the Dublin Fringe Festival. However, following a campaign from local residents to restore "Wolfe Tone Park as a non-commercial green space", there has been an ongoing debate in the Council as to the future use of the park.
Wolfe Tone Park, sometimes known as Wolfe Tone Square, is a public space in Dublin, Ireland. Named for Theobald Wolfe Tone (1763–1798), the park is the site of a graveyard that was attached to St. Mary’s Church. The graveyard was deconsecrated in 1966 and laid out as a green park. In 1998, Dublin City Council held an international competition to redesign the park, which was won by Peter Cody of Boyd Cody Architects. The park in its current form was completed in 2001.
The park is the final resting place of the United Irishman Archibald Hamilton Rowan (1751–1834), Mary Mercer, founder of Mercer's Hospital (died 1734), the philosopher Francis Hutcheson (1694–1746), Sir Boyle Roche, 1st Baronet (1736–1807), an Irish politician and member of the Irish House of Commons, parish rector William Fletcher (1715–1771), and Lord Norbury (1745–1831; known colloquially as the hanging judge).
