The plaque says it all.

In August 1787 Robert Burns, aka Rabbie Burns, often regarded as the national poet of Scotland, undertook a Highland tour. The Crosskeys Inn was his first overnight stop having set off from Edinburgh. He arrived from “that dirty, ugly place Borrowstoness” (Bo’ness) and spent the night with his travelling companion at the Inn, in Falkirk High Street. It was one of many inns and taverns in the town; the town’s top coaching inn, the Red Lion, was full of cattle drovers and buyers in Falkirk for the September Tryst, so he settled here. Burns stayed the night and scratched a short poem on a window; that window is on display in the Burns museum in Alloway. The Crosskeys is now the Revolution Music shop.
His short visit to the area continued the next day - firstly to a nearby churchyard, then he crossed the “Grand Canal” in Camelon, and went on to Carron Ironworks, (maker of cannons, cannonballs etc), where he was refused entry (a Sunday). Subsequently Burns and his companion went across the road to the Carron Inn and he scratched an angry poem on the window of the hostelry.
A month later he apparently returned and got his tour of the Carron Works.
