What an interesting, fun museum!
The focus is on Irish emigration, the Irish diaspora, and the influence of Irish culture around the world.
The exhibits are arranged by category (e.g., arts, storytelling, sport). This was an accessible way to organize the narrative with the bonus that you could spend a lot of time in sections of most interest to you and move more quickly through others. For our group, that was especially nice -- for example, one person went really into sports while I spent a lot of time in art.
The exhibits are also arranged in a way that allows you to pick how in-depth you want to go. It's easy to get a general overview from the main parts of each exhibit, but you also also interact with the technology to go more in-depth.
And the use of technology is excellent. It's impressive but actually functional and useful to learning, versus just for gimmick.
Definitely worth the price of admission and a great way to learn more about the Irish soul and character.
