www.op.org, available in the three official languages of the Order (English, French and Spanish), is the official international Web site of the Order of Preachers (the Dominicans).
It provides a wealth of information about the Dominican Order, and not simply about the Dominican friars. It is the principle source for links to the websites of Dominican entities throughout the world.
The Dominican monastery of Catherine of Siena, located just outside the town of Drogheda, Co Louth, is the sole monastery of Dominican nuns in the British Isles. The nuns present their lives of prayer and their work on this site.
This is the website for the Irish congregation of Dominican Sisters, the Cabra congregation. The sisters share some glimpses of their lives and work, with some resources for prayer also offered.
