The Irish Open was already expected to attract enormous attention when it moved to Trump International Golf Links in Doonbeg, County Clare. With the US president due to arrive in Ireland on September 12 and attend the closing stages of the tournament, however, the focus is no longer limited to Rory McIlroy, Jon Rahm and the rest of the elite field.

According to a newly published report by The Clare Echo, Doonbeg will host Ireland’s largest security operation of 2026. Hundreds of Garda officers are expected to be deployed across West Clare as the village prepares for Trump’s arrival.

An Irish village enters lockdown

Parking will be banned in Doonbeg from September 8, one day before the wider tournament programme begins. The N67 will then be closed to general traffic from September 11, while residents inside parts of the security cordon will require either a Garda pass or identification and proof of address to reach their homes.

Golf spectators will not be permitted to drive directly to Trump International Golf Links. Sergeant Edel Burke confirmed that “entry to the event is strictly through the Park and Ride and/or shuttle buses”, with visitors required to register their vehicle in advance. Police have also warned that cars left on surrounding roads could be towed.

The restrictions will be introduced during the decisive weekend of the DP World Tour event. According to the official Irish Open spectator information, the event runs from September 9 to 13, beginning with the Wednesday Pro-Am before the four competitive rounds take place from Thursday to Sunday.

Trump is expected to arrive in Ireland on Saturday, September 12, before visiting the resort owned by his family’s business. He is then expected to attend the final stages of the tournament on Sunday, although the precise details of his movements are likely to remain restricted for security reasons.

The military has opened the Octagon

The operation extends far beyond additional police officers and traffic barriers. As described in a Press Association report published by BreakingNews.ie, the Irish Defence Forces will coordinate support from a special command centre known as the Octagon at McKee Barracks in Dublin.

The centre brings intelligence, logistics, land, maritime, air and cyber capabilities under one command structure. It can also coordinate counter-drone units, bomb disposal teams, air policing and maritime security when requested by An Garda Síochána. Ireland’s military said it was the first time those different operational areas had been synchronised in this way under a single commander.

The system was established as part of Operation Fianna, which also supports security during Ireland’s presidency of the Council of the European Union. Trump’s visit creates an additional challenge because it coincides with the resumption of high-level European meetings following the August break.

Reports have suggested that the presidential delegation could include as many as 1,000 people, including approximately 200 Secret Service personnel. Those numbers have not been formally confirmed by the White House, but hotels across County Clare and the wider region have reportedly faced intense demand ahead of the visit.

McIlroy and Rahm risk being overshadowed

The political spectacle threatens to take attention away from one of the strongest Irish Open fields in recent memory. Defending champion Rory McIlroy will be joined by Jon Rahm, Shane Lowry, Pádraig Harrington, Patrick Reed, Tyrrell Hatton and five-time major winner Brooks Koepka.

According to the DP World Tour’s announcement of Koepka’s participation, weekend tickets have already sold out. Koepka said he was “excited to experience the challenges of links golf at Doonbeg for the first time” as he prepares for his second appearance at the Irish Open.

McIlroy is attempting to win the national championship for a third time after reclaiming the title at The K Club in 2025. Rahm, meanwhile, is seeking his third Irish Open victory, while former champions Lowry and Harrington add further Irish interest to the tournament.

Trump could also play a visible role during the closing ceremony. Local reports have suggested that either the president or his son Eric Trump may be involved in presenting the trophy, but the DP World Tour has not publicly confirmed who will perform that role.

A private golf resort backed by a public operation

The unusual setting creates an unavoidable political and commercial dimension. Trump is not simply visiting a major international sporting event as president, because the tournament is being held at a resort purchased by the Trump Organization in 2014 and still carrying the family name.

According to an earlier report by The Clare Echo, the overall security operation has been estimated to cost more than €20 million, with thousands of people potentially involved in planning and logistics. That estimate has not been confirmed as a final figure by the Irish authorities, and providing security for a visiting US president would be required regardless of who owned the venue.

The visit nevertheless gives the Trump family’s property a level of global exposure that few golf resorts could purchase. Local councillor Michael Shannon argued that Trump’s presence could bring investment and valuable international attention to West Clare, saying: “You can’t buy that publicity.”

For the DP World Tour, the week was designed to showcase world-class links golf and one of the strongest fields of the season. For Trump, it offers a global stage at a resort bearing his name, with Ireland’s security services building an operation of exceptional scale around him. For the people of Doonbeg, it means their quiet coastal village will briefly become one of the most heavily protected places in Europe.
