Oatlands College

The Christian Brothers first established a community in 1951, before opening the school in 1955. It is now under the Trusteeship of the Edmund Rice Schools Trust. The school added a single storey extension in 1969 and later added a sports hall in 1980. After some modernisation in 1995, the school opened a new wing in 1999.[2] In the summer of 2010, a new technology room, drawing room, music room, a second computer room, two new class rooms and two new science laboratories were added to the building.[3] On 10 May 2012, a new sports hall with a canteen and a new classroom was opened by the President of Ireland Michael D. Higgins.[3] The school is served by Dublin Bus routes 7b, 7d, 46a, 46e, 47, 116, 118, 145 and 155 along the N11 Stillorgan Road Quality Bus Corridor. The school itself is located about 2 minutes walk to Stillorgan village.
