The Spanish Embassy has identified parts of Dublin as "medium risk areas."
It follows a number of violent incidents in the city this summer.
A note on the Embassy's website advises tourists to take "special precautions" in certain places.
It says street fights are "frequent" in Temple Bar, Portobello, O'Connell Street, Parnell Square and near Connolly Station.
Violence Was Predicted
Meanwhile, over half of social workers surveyed during the pandemic predicted a rise in youth violence.
The Irish Youth Foundation asked 350 child service officers what they believed the future for children and teens in Ireland would look like.
They predicted a rise in anti-social behaviour and violence, as well as an increase in school dropouts among those in disadvantaged communities.
CEO of the Irish Youth Foundation, Lucy Masterson, says a lack of support in these areas has resulted in some teens lashing out:
"If you are a young person growing up in a community that is being tarred like this, it is really difficult to keep the head high."
Lucy says a strong education is a "passport" into a thriving future.
However, many young people have had their development "arrested" in the last few years, Lucy says.
