19 Toberwine Street, Glenarm, Ballymena, Co Antirm, BT44 0AP

19 Toberwine Street is a small, plain, two-storey terraced house on the west side of Toberwine Street in Glenarm, County Antrim. It possibly dates from before 1832 in origin, though its current front façade is the result of alterations carried out around 1990, which involved the removal of a later 19th-century shop front that had itself been inserted at some point after 1859, probably around 1880.

The front elevation faces east and is asymmetrical. On the ground floor, a panelled door with a plain rectangular fanlight sits to the far left, with two plain sash windows to its right. The first floor has two further plain sash windows positioned directly above those on the ground floor. The façade is finished in painted lined render. The gabled roof is slated and features a small Velux window to the front and at least one to the rear. There is a rendered chimneystack to the north and a brick chimneystack to the south. Metal rainwater goods are fitted to the front elevation. The rear elevation was not inspected. The property is within a conservation area but is not listed, as it does not meet the criteria for listing and is not considered to be of special architectural or historic interest.

Historical records place a building on this site as far back as John O'Hara's 1779 map of Glenarm, the earliest known plan of the village. The first valuation of 1833 records a relatively old dwelling of similar dimensions to the present building, with a James McFalls listed as resident. By the time of the 1859 valuation, the occupant was the Reverend Patrick Starkey, a local Roman Catholic priest, and the property is recorded as containing two rooms on the ground floor, three above, and a garret.

Toberwine Street — whose name translates from the Irish as "street of the sweet well" — is thought to represent the original core of the village of Glenarm. Its narrowness is taken as an indication of its antiquity. The original 13th-century castle of Glenarm, around which the village grew, is believed to have stood at the south-west corner of the street, on the site now occupied by the former courthouse. The castle was deliberately destroyed by Sorley Boy MacDonnell in 1597 and was apparently not repaired; his descendant Sir Randal McDonnell subsequently built a new residence on the opposite side of the river. Some historians record that the old castle was occupied by tenants in the later 17th century, implying it was repaired to some degree, but Richard Dobbs makes no mention of it in his 1683 description of the village. The 1835 Ordnance Survey Memoirs refer to "the foundations of a very extensive old castle which stood at the centre of the town until a few years ago," suggesting that some ruins survived into the early 19th century, though nothing verifiable appears on O'Hara's 1779 map.

The earliest known reference to "Toberwine" in the Antrim Papers is a lease of November 1672 mentioning a house in the area, with "Toberwine Street" named explicitly in a lease of August 1709. O'Hara's 1779 map shows the street fully built up on both sides, with a market and courthouse at the south-west end. Evidence from the 1833 valuation suggests that most buildings now visible on the west side of the street were present in some form by that date, and many are thought to be 18th-century in origin. The east side of the street saw considerably more development after 1833, with nos. 4–12 dating from around 1840, and nos. 20–34 and 62 from after around 1860, some replacing earlier single-storey dwellings.
