Every Saturday morning (weather permitting) at the every civilised hour of 11am, a little magic happens in Dartmouth Square, Dublin 6. Louise Horgan and her acolytes convene, whip out their mats and set to it on the lawn. If you're lucky, the best €5 (minimum donation) you'd ever spend on body and soul will have you literally saluting the sun. Last year classes ran right through October. Guest teachers also do stints so look for updates @DartmouthSquare.
