St Joseph's College was established in 1862 due to the absence of a Catholic Intermediate School for boys in the city. Bishop John McEvilly asked Brother Paul to open such a school and St. Joseph's Seminary was established at Nuns' Island in 1862. Due to the bishop's close association with the school, the seminary was generally referred to as "the bishop's school" and to this day is known as "The Bish." Publicising his new enterprise Bishop McEvilly wrote a pastoral in which he stated: "For many years we have had excellent schools for the lower orders at the Mercy Convent, Newtownsmith, and the Monastery School at Lombard St. The higher class of boys are catered for at St. Ignatius' College, the girls at the Dominican Convent. Now, at last, we happily have a school for the middle class at St. Joseph's Seminary, Nuns' Island." When the school was established the word seminary had no ecclesiastical connotations and there was in fact a "Seminary For Young Ladies" further down Nuns' Island, by the 1930s the word had come to mean a college for the training of candidates for the priesthood, and at the express desire of Bishop Michael Brown the Brothers changed the name to "St. Joseph's College", and in the 1970s Bro. Valerian Whelan inserted the word Patrician in the title. In 1899 a National School was opened to cater for the Junior Classes at the Seminary and it too came to be known as "The Bish". In 1930 the Brothers acquired the bonded store belonging to Persse's Distillery, renovated it and transferred the seventy Intermediate pupils across the road. The National School took over the rooms vacated on the original site and continued in operation until 1954 when it and "the Old Monastery School" were replaced by St. Patrick's, on Lombard Street.
Extra curricular activities

Plays and talent shows are often performed annually by the students of St. Joseph's Patrician College.
Rowing
St Joseph's College Rowing Club was established in 1932, making its first competitive appearance against St. Patrick's Boat Club later that year in the Schoolboy Fours. It did not acquire its own boathouse until 1955, when the Menlo Emmet's donated their Woodquay premises to the school under the agreement it should never be used for anything but the development of rowing. The club was a dominant player in the Junior National Championships which had been established in 1964, and has won a number of national championships in various grades. Internationally, oarsmen from St. Joseph's College R.C. have also excelled, as a club competing at The British School Regatta, Ghent International Regatta, Henley Royal Regatta, and the Sydney International Rowing Regatta in March 2013. Many have represented Ireland on the international stage at all levels of competition from the Home International Regatta, to the Coupe de la Jeunesse and the World Junior Championship. Alumni of the school have achieved even higher laurels following on from their experience gained on the Corrib, competing at the World U-23 Championships, World Senior Championships and the Olympic Games.
