This is, in my opinion, the most outstanding feature of Dublin. Yes, their colorful doors. This unique feature sure makes this city stand out from all other cities that I've visited thus far. They are so bright and colorful; and can be found at every street corner.
For the really nice doors, I'd highly recommend that you check out those cool Georgian houses along Merrion Square.
Merrion Square itself is a very fine example of Georgian Dublin and a stroll around the square will give you a first hand experience of the famed Doors of Dublin now immortalized in a famous poster of the same name.
A stone's throw away, along Kildare Street, you can catch a glimpse of Dáil Eireann (read: the House of the Irish Parliament). Also on Kildare Street is The National Library which frequently houses art and photographic exhibitions, and the Taylor Galleries of Contempory Modern Art. All must-sees if you ask me.
Unfortunately, I didn't have much time to visit the museums.... but I passed it almost every other day! Big deal huh?
