The University of Wales Trinity Saint David is a collegiate university operating on three main campuses in South West Wales: in Carmarthen, Lampeter, and Swansea. The university also has a fourth campus in London, England. It came into existence through the merger of the two oldest higher education institutions in Wales, the University of Wales, Lampeter (UWL), and Trinity University College (TUC) in 2010, under Lampeter's royal charter of 1828.
Both Trinity and Lampeter each had positive reputations in separate areas. Whilst Trinity had a good reputation for the arts and vocational training for areas such as teaching, Lampeter historically enjoyed a reputation as the best university in Wales for research. The merger of the universities has aimed to ensure that these two reputations survive and the new university has recently gained a good reputation for its research particularly in the area of religion and the humanities and for personal development.
The university is the first in the UK to place at its core sustainable development. The university's Institute of Sustainable Practice and Resource Effectiveness or INSPIRE is designed to ensure that students are prepared for their futures in the workplace and in society as a whole.
