Down High School

The Gate House and stone walls surrounding the school were originally part of the County Gaol. The stone walls were lowered to the deck when the school was established. It was argued that removing the walls completely would allow fog from the nearby River Quoile to rise into school grounds. There were tunnels beneath the school and grounds (that now are sealed off) which were used to transport prisoners to and from the court house on English Street. Convicts sentenced to death would often be hanged in the main gateway in front of the school. The large granite gatehouse is a prominent feature of the Mount Crescent area, and lies unused. Many of the classes are taught in temporary classrooms.

The school's crest, designed by the late RWH Blackhood of Loughinisland near Downpatrick, is a reminder of another link with the past, dating back to the 12th Century. The design itself is based upon the supposed badge of John De Courcy, the Norman soldier who captured Downpatrick in 1177 and established himself as the ruler of the North East of Ireland. The colours of the crest are taken from the arms of the Anglo-Irish aristocrat, Lady Elizabeth Cromwell (1674–1709), the daughter of the 4th Earl of Ardglass, and owner of the Downpatrick estate. Lady Elizabeth was wife of the Rt Hon Edward Southwell, MP for Kinsale, and Principal Secretary of State for Ireland in the reigns of King William III and Queen Anne. Southwell was a well known benefactor of the town.

The school's motto Floreat Dunum, Absque Labore Nihil means 'May Down Flourish, nothing is achieved without effort'. 'Floreat Dunum' appears on the blazer badge of the school.[2] Previous pupils are known as "Old Dunumians".
