Why the news keeps calling
The coldest place
Katesbridge's Met Office weather station sits about a mile and a half out of the village in a shallow natural bowl. On clear, calm nights — the kind that follow a cold front and clear by midnight — cold air drains off the surrounding higher ground and pools in the hollow. The result is what meteorologists call radiative cooling on steroids. The site holds the all-time minimum of -17.8°C, set on 21 December 2010, and routinely records the lowest UK temperatures of both winter and, oddly, summer. Mark Vogan, the Scottish meteorologist who visited the station in 2017, called it Northern Ireland's icebox. The locals call it Tuesday.
The woman the bridge is named for
Kate McKay
The eponymous Kate was born in nearby Ballyroney in 1691. By the mid-eighteenth century she was living in the house where the workmen building the new stone bridge over the Bann boarded during the construction. The workmen, by tradition, found her so good a landlady that they named the new bridge in her honour. The hamlet that grew up around the bridge took the bridge's name. There is no statue. There is no plaque. There is just a place that still carries her first name two and a half centuries later, which is a quieter monument than most.
Banbridge to Castlewellan, 1880–1955
The branch line
The Great Northern Railway opened a branch from Banbridge to Ballyroney in 1880, with a station at Katesbridge from day one — 14 December 1880. In 1906 the line was extended on to Castlewellan, where it met the Belfast and County Down Railway's branch from Newcastle. For seventy-five years a small country station here connected the village to Belfast, Dublin and the sea. The line closed on 2 May 1955 in one of the era's mass closures. The station building is gone. The cuttings and embankments are still readable in the fields if you know where to look.
