The Garda in charge of our national security says officers could respond to a terrorist attack in Temple Bar "within a matter of minutes".
Assistant Commissioner Michael O’Sullivan has been speaking at a major Interpol conference, which is being held in the city centre today.
The threat level to Ireland remains moderate – meaning an attack is possible but not likely.
However, Assistant Commissioner O’Sullivan says gardai are ready should one happen.
"We looked at a similar target to London Bridge, which we identified as Temple Bar", he explained.
"There were three heavily-armed cars within three minutes, there were two ER units on standby at Harcourt Square, and a further two Armed Support Units in North Dublin who would respond in seven minutes".
The Assistant Commissioner said he is "quite happy" with response times.
The Justice Minister Charlie Flanagan said he also believes we’re prepared. "We don't have any evidence of an immediate or prepared attack, but we are always monitoring international movements", he said.
Lone wolf attacks always pose a serious threat and have been described as probably the greatest concern to all Police Services in Europe.
The assistant commissioner added gardai are monitoring a small number of Isil sympathisers here.
