The actor has commented on the "bottleable" smell of Trinity College
British actor and presenter Richard E Grant is spending a while in Dublin - and tweeting his way though it all.
He has starred in several films, including 'Bram Stoker's Dracula', 'Jack and Sarah' and 'The Iron Lady'.
His TV work includes 'Game of Thrones', 'Downton Abbey' and 'Doctor Who'.
The 59-year-old has also visited extremely expensive hotels around the world in 'Richard E Grant's Hotel Secrets' - one of which involved a trip to Ireland in 2012.
It saw him take in Galway, Belfast, Monaghan, Dublin and Laois.
Tourism Ireland has since confirmed Mr Grant is actually in the capital to launch a €9m promotional campaign.
It is hoped this will boost late-season travel to Ireland from around the world, as the September to December period usually yields as much as 30% of Ireland's annual overseas tourism business.
As part of the campaign, the actor is filming two online videos for a promotion with Smooth Radio in Britain, which will reach about 5.5 million potential holidaymakers.
He arrived in the city and started tweeting to his more than 110,000 followers on Monday morning, beginning with the Sean O'Casey Bridge:

He then moved on to the Ha'penny Bridge, calling himself a "Tourist-happy snappy":

The star also visited College Green and Trinity College, commenting on the "'Simpsons' looking CGI sky":

Further inside the building, he found himself in the Long Room library.
He said: "Trinity has the most unique smell. Of wood and beeswax and old books that is bottleable!"
