A plaque detailing the key events in Otley's history will be officially unveiled on Thursday.
The brainchild of resident John Morgan, helped by Jo Allen, the blue plaque has gone up on the front outside wall of The Bay Horse pub on Market Place.
Mr Morgan led a team of volunteers who produced a book, Otley – Past, Present and Future, to commemorate the Queen's Silver Jubilee back in 1977.
The publication was updated for the Golden Jubilee in 2002 and proceeds have helped fund local community projects.
Mr Morgan came up with the plaque idea as a way of marking 2012's Diamond Jubilee.
He said: "We had some money left over and I thought a historical plaque for the town would be a good idea.
"So we set about getting it designed, getting it made and getting permission for where to put it in the Conservation Area, which took nearly two years.
"It outlines some of the main events and dates in the town to give visitors an idea of its past and how it expanded as a Victorian industrial and a market town."
The plaque will be unveiled by MP Greg Mulholland (Lib Dem, Leeds North West) at 6.30pm.
