Pearse Street Garda Station is not the obvious choice of destinations for most tourists.
But Hollywood actor Michael Rooker made it top of his must-see places in the city.
The American actor, who is known for playing Merle Dixon in popular series The Walking Dead, has been enjoying some time in the capital when he visited one of the city's less obvious landmarks.
The Guardians of the Galaxy star is in Ireland to attend this weekend's Comic Con in the Convention Centre and he revealed he wanted to visit the city centre garda station when he arrived in Dublin - joking that he was in town to lend a hand.
"They're severely understaffed so they brought me in for a little help," the actor laughed.
"I ended up there because one of the officers there is part of our Comic Con. He knows that I'm pro-law enforcement," Michael explained on Today FM.
"I'm a very big [fan] of the police. They're usually understaffed everywhere and they need a lot of help."
Rooker was also spotted strolling around the shops on Grafton Street with his wife Margot.
As he went on a sightseeing trip of the city the 60-year-old happily posed for selfies with fans.
The screen star, who hails from Alabama, is set to appear at Dublin's third annual Comic Con, which kicks off today.
The two-day sci-fi extravaganza, which is based on the world-famous Comic Con in San Diego, is set to attract over 16,000 fans.
Rooker isn't the only big name Irish fans will be turning out to see at the event, as Star Trek actress Gates McFadden and Buffy the Vampire Slayer star Nicholas Brendon are also in Dublin for the weekend.
Brendon, who played Xander in the popular series, previously pulled out from appearing at this weekend's Comic Con due to his struggle with depression.
However, he recently reconfirmed that he would come to the Dublin event, accompanied by his former Buffy co-star Emma Caulfield.
Also on the bill are Stargate's Alexis Cruz, Billy West from Futurama and V for Vendetta actor David Lloyd.
