Named after two Danish words for measurements of butter, the Firkin Crane is set in a quirky Victorian-era rotunda on the North Bank, just downhill from St. Anne’s Church. It’s one of Ireland’s major centers for contemporary dance, hosting touring companies in addition to showcasing new talent. Many performances are free. The only downside is that performances are infrequent—usually just a handful per month—and the most headline-grabbing tend to be during the Guinness Jazz Festival.
