Five of the six counties are hosting a demonstration, with Co Tyrone hosting two separate parades.

Sir Knights in Fermanagh held a successful demonstration earlier this month, as is long-established, to mark the Battle of Newtownbutler in 1689.

Up to 40,000 participants are expected to be in attendance across the various venues with many more watching from the sidelines.

The largest gathering will take place in Dromore, Co Down as members of approximately 120 preceptories representing a total of 13 districts descend on the town, accompanied by some 100 bands.

This parade will include the biggest preceptory turnout, Elijah's Chosen Few RBP 208 from Kilkeel, which has a membership of 250 alone.

The smallest demonstration will take place in Sion Mills as 30 preceptories from the surrounding border area congregate at the west Tyrone village.

As is traditional, Belfast-based Sir Knights hold their annual demonstration outside of the city. This year, their parade venue is Portadown where a large contingent of visitors is expected from Scotland.

Sir Knights will also be on the march in Ballyclare, Londonderry and Dungannon.

Imperial Grand Registrar Billy Scott is expecting an "excellent day" for the institution as they bring the curtain down on another successful marching season.

"The Last Saturday is the last of the major demonstrations of the summer and is traditionally very much a family occasion," he said.

"This year we are looking forward to something similar and are hoping and praying for favourable weather conditions."
