Orangemen parading in Portglenone will participate in the only Twelfth demonstration in Northern Ireland which takes place in two counties!
Sixteen lodges walking in the Triangle parade will commence their parade in Co Antrim and proceed to a religious service, held in neighbouring Co Londonderry.
In other years, Ahoghill and Cullybackey are the venues for one of the most close-knit demonstrations in the Province.
Despite its smaller size, there will be plenty of noise, with at least half of the lodges being accompanied by Lambeg drums, adding to the carnival atmosphere.
A mixture of bands will also partake, with Cullybackey LOL 696 Flute Band, only recently formed, taking part in its first Triangle Twelfth.
The main parade will commence at 12.30pm on the Cullybackey Road, with lodges and bands proceeding through the village to the demonstration field on the Clady Road.
