1. Dublin has over 750 pubs. That’s right — you could visit two a day for an entire year and still not get through them all. Cheers to that! (Reference)
2. The name “Dublin” comes from the Irish “Dubh Linn,” meaning “black pool” — referring to a dark tidal pool where the River Poddle met the Liffey, near Dublin Castle.

31. There’s a mummified cat and rat on display in a church crypt. You can find them frozen mid-chase in the crypt of Christ Church Cathedral — stuck in an organ pipe since Victorian times. Creepy, but iconic.
