The Office of Public Works (OPW) and An Garda Síochána have announced a temporary 43-hour full lockdown of Dublin's Phoenix Park and Dublin Zoo to facilitate security arrangements for an upcoming visit by US President Donald Trump.

According to an official statement from the OPW, all vehicular and pedestrian gates across the park will be closed starting at 11:00 p.m. on Thursday, September 10, and will remain locked until 6:00 p.m. on Saturday, September 12. The agency confirmed that the security measures were requested by police for operational reasons, adding that gates and thoroughfares will reopen as soon as it is safe to do so. Access during the closure period will be restricted strictly to essential staff working within the park grounds.

In conjunction with the park-wide security closure, Dublin Zoo confirmed on its website that it will be closed to visitors on Friday, September 11, and Saturday, September 12. The move affects one of Ireland's primary tourist attractions located within Europe's largest enclosed urban public park, which typically remains open to the public around the clock.

President Trump's itinerary in Dublin includes scheduled engagements within the Phoenix Park, including a meeting with Irish President Catherine Connolly at Áras an Uachtaráin on Saturday morning, followed by bilateral talks with Taoiseach Micheál Martin at Farmleigh House. Following his engagements in the capital, the US president is scheduled to travel to County Clare to attend the Irish Open golf tournament at his resort in Doonbeg.
