There are two editions and translations of two different medieval hagiographies of Saint Brigid available on CELT:

The living tradition of St. Brigid in Kildare is kept by the Brigidine Sisters at Solas Bhríde in Kildare. Amongst much other work, they celebrate St. Brigid’s Day, Lá ‘le Bhríde, every February 1st at St. Brigid’s Wayside Well and Garden Well. The Wayside Well is right beside the entrance to the Japanese Gardens and National Stud, just outside Kildare town, and the Garden Well is a short walk away, off the main road.
I have been to this celebration twice, and it is an uplifting, inclusive event. On the eve of the festival, folk gather by candlelight at the Wayside Well, and then process to the Garden Well, where there is often a great bonfire lit. The following day is full of tours of the countryside, including sites important to St. Brigid, and talks on everything from history, folklore and mythology to social justice.
