The Castlebar Campus of the Galway-Mayo Institute of Technology, enrolled its first student in September 1994. The campus development plan at Castlebar envisaged a full-time student population of 400 in 1996, 550 in 1997 and 1,000 students by the turn of the century. Students in Castlebar enjoy the advantages of being part of a relatively small student population with a high staff to student ratio while reaping the benefits of being associated with a well established college of high reputation.

The Castlebar Campus is located on approximately 30 acres in the heart of Castlebar. The campus with its extensive mature grounds and elegant buildings constitutes a pleasant and productive environment for study. The campus allies technologically advanced educational to advanced educational methodologies.

Current facilities include modern computer laboratories, electronic laboratories, science laboratories, a language laboratory and a well equipped library. The Campus also has excellent social, recreational and sporting facilities.

The college offers a wide range of services covering such areas as accommodation, health, counseling, careers and a chaplaincy. An active Students Union, which oversees the numerous clubs and societies, provides further services to students. Students are encouraged to become involved in the sporting and cultural aspects of College life and a variety of clubs and societies ensures that most interests are catered for.

With its central location, Castlebar enjoys easy access to both Ireland West Airport Knock and the famous western seaboard regions of Achill, Clew Bay, and Connemara. As the county town of Mayo, Castlebar has the infrastructure and facilities usually found in larger cities. In recent years many modernised facilities have been added to the town, making it a model for regional development.

The establishment of a new third-level college in Mayo in 1994 was a further expression of the progressive, dynamic spirit in the area. By putting its experience and prestige behind the Castlebar campus development, Galway-Mayo Institute of Technology made a commitment to state-of-the-art technical and commercial training in Castlebar.
