Oberstown Children Detention Campus

Trinity House Reformatory School, a high-security institution, was opened in 1983. Oberstown Boys School and Oberstown Girls School opened in 1991. The three schools merged in 2016.[6][7]

In 2016, a riot led to a major fire and the deployment of armed gardaí.[8][9]

In 2017, two offenders escaped after attacking a staff member with a crowbar. They were quickly recaptured.[10]

In May 2020, "Boy A", one of the murderers of Ana Kriegel, was assaulted by other residents.[11]

The deputy director describes it as "not a prison" and that residents are not prisoners, but "young people in conflict with the law."[8] Their model of care is built around "care, education, health, offending behaviour, and preparation for leaving."[12] There are two separate schools, Oberstown Boys School and Oberstown Girls School, operating under the patronage of Dublin & Dún Laoghaire Education and Training Board.[13][14]

About one-fifth of residents are Irish Travellers, while 71% have substance misuse issues.[15]

After release, residents return to their families or are placed in the care of Túsla. Those serving long sentences are transferred to adult prisons at the age of ​18 ¹⁄₂.[8]

Due to laws protecting juvenile offenders, residents can in general not be publicly named.

• "Boy A" and "Boy B", teenage murderers of Ana Kriégel
• The murderer of Lorcan O'Reilly[16]
