O'Brien Institute

The O'Brien Institute is a building complex off the Malahide Road, near Mount Temple Comprehensive School in Marino, Dublin, Ireland.

Built in 1880–1883 as an orphan home and school, the purchase of the land, and building costs, were financed by a trust that was founded by the will of Bridget O'Brien in 1876.

Funding has been provided for books, equipment (IT, music and special materials for those needing specific sensory stimulation), sporting facilities, extra-curricular and after-school activities, and assessments.

Archbishop John McQuaid organised the transfer of the land, and construction began on the new home months before planning permission was granted.

The development was a significant encroachment on the neighbouring Casino, obstructing the vista of the ornamental building from the road.
