Blackrock College

Blackrock College is a Catholic secondary school in Dún Laoghaire–Rathdown situated on a 56-acre campus that stretches along Dublin Bay and serves both boarding and day students. The school offers instruction in traditional subjects such as Latin and German as well as in contemporary areas like science, art, and business studies for students aged 13 to 18 years old.

The school was founded in 1860 by French missionary Jules Leman and originally served to train missionaries in the Catholic faith. It later developed into a broader educational institution for secondary students in the region.

Students participate in annual opera productions, debates, athletic competitions, and engage in social work initiatives supporting local and international charitable organizations.

The grounds can be explored on foot, with the path along Dublin Bay being particularly rewarding and offering pleasant views. Visitors should expect that certain areas of the campus may not be accessible to the public during school hours.

The campus houses Williamstown Castle, an 18th-century structure from 1780 that now serves as a residence hall for boarding students during the academic year. The castle gives the educational grounds a historical character that becomes apparent when walking through the campus.
