The station, which is 67¾ miles from Belfast, was opened on 4 December 1855.
 To accommodate excursion and holiday traffic, extensive reconstruction by the Belfast and Northern Counties Railway, under the direction of its engineer and architect Berkeley Deane Wise, was completed in 1893.
 Three platforms were provided (only one is now in regular use) together with a train shed (demolished) and a station building in a "half-timbered" Mock Tudor style with a clock tower, described by Currie as "certainly one of the most handsome railway buildings in Ireland"; it is now occupied by a retail unit, with a small newer concrete block ticket office behind it serving as the current station building.
 Goods traffic to the station closed on 20 September 1954.
Historia Norwegiæ is a short history of Norway written in Latin by an anonymous monk.
 The only extant manuscript is in the private possession of the Earl of Dalhousie, and is kept at Brechin Castle, Scotland.
 However, the manuscript itself is fragmented; the "Historia" itself is in folios 1r-12r.
 Recent dating efforts place it somewhere c. 1500-1510A.

Historia Plantarum (also called Conradi Gesneri Historia Plantarum) is an extensive botanical encyclopedia by the Swiss natural scientist, Conrad Gessner (1516 – 1565).
 Although compiled between 1555 and 1565, it was not published till after 1750, since he died of the plague, prior to its completion.
 To complete the work, he amassed a collection of some 1,500 drawings of plants, most of which were his own work.
 The scale and scientific rigour were unusual for the time, and Gessner was a skilled artist, producing detailed drawings of specific plant parts that illustrated their characteristics, with extensive marginal notation discussing their growth form and habitation.
