We've picked out some of the festival highlights for your touring pleasure.
This is definitely top of our list. The social media headquarters is open to visitors for special tours so you can see what goes on behind the slick doors, designed by Frank Gehry, one of America’s best-known architects.

It's worth getting up here for the view alone.
This is a hidden gem on the northside, a mid-18th century Georgian town house with an incredible hidden garden.
We never knew this even existed.
Take a peek inside this historic building which is being reconstructed. It's right next to the St James's Gate brewing district.
Originally part of Dublin Corporation’s 1930s Crumlin housing scheme, this gaff is now an Airbnb dream house.
It won Best House Extension Award in the 2013 Irish Architecture Awards and it personifies house goals.
