Sister college in the context of "University of Dublin"

Somerville College is a constituent college of the University of Oxford in England. It was founded in 1879 as Somerville Hall, one of its first two women's colleges. It began admitting men in 1994. The college's liberal tone derives from its founding by social liberals, as Oxford's first non-denominational college for women, unlike the Anglican Lady Margaret Hall, the other to open that year. In 1964, it was among the first to cease locking up at night to stop students staying out late. No gowns are worn at formal halls.

In 2021 it was recognised as a sanctuary campus by City of Sanctuary UK. It is one of three colleges to offer undergraduates on-site lodging throughout their course. It stands near the Science Area, University Parks, Oxford University Press, Jericho, and Green Templeton, St Anne's, Keble and St Benet's. Over a third of its 650 students are not from the UK. Over half the UK admissions are from state schools – close to the university average. Its total net assets in 2021 were £238 million, the seventh highest of an Oxford undergraduate college. Its sister college at Cambridge is Girton.

Trinity College Dublin (Irish: Coláiste na Tríonóide, Baile Átha Cliath), officially branded by the board as Trinity College, the University of Dublin, and by decree as The College of the Holy and Undivided Trinity of Queen Elizabeth near Dublin, is the sole constituent college of the University of Dublin in the Republic of Ireland. Founded by Queen Elizabeth I in 1592 through a royal charter, it is one of the extant seven ancient universities of Great Britain and Ireland. As Ireland's oldest university in continuous operation, Trinity contributed to Irish literature during the Victorian and Georgian eras and played a notable role in the recognition of Dublin as a UNESCO City of Literature.

Trinity was established to consolidate the rule of the Tudor monarchy in Ireland, with Provost Adam Loftus christening it after Trinity College, Cambridge. Built on the site of the former Priory of All Hallows demolished by King Henry VIII, it was the Protestant university of the Ascendancy ruling elite for over two centuries, and was therefore associated with social elitism for most of its history. Trinity has three faculties comprising 25 schools, and affiliated institutions include the Royal Irish Academy of Music, the Lir Academy, and the Irish School of Ecumenics. It is a member of LERU and the Coimbra Group. Trinity College Dublin is one of the two sister colleges of both Oriel College, Oxford, and St John's College, Cambridge, and through mutual incorporation, the three universities have retained an academic partnership (Oxon, Cantab, and Dubl) since 1636.

Girton College is a constituent college of the University of Cambridge. The college was established in 1869 by Emily Davies and Barbara Bodichon as the first women's college at Cambridge. In 1948, it was granted full college status by the university, marking the official admittance of women to the university. In 1976, it was the first Cambridge women's college to become coeducational. Its sister college is Somerville College, one of the two Oxford colleges to first admit women.

The main college site is situated on the outskirts of Girton, about 2+1⁄2 miles (4 kilometres) northwest of the university town, and comprises 33 acres (13 hectares) of land. In a typical Victorian red-brick design, most was built by architect Alfred Waterhouse between 1872 and 1887.
