Prince Charles and Camilla are to visit Halifax and Haworth next week.
Their Royal Highnesses The Prince of Wales and The Duchess of Cornwall are coming to West Yorkshire later this month.
The pair will start their trip, on Friday 16 February, at The Piece Hall in Halifax and will mark the occasion by ringing the original trading bell and unveiling a new commemorative plaque. They will also visit nearby Square Chapel Arts Centre and Dean Clough.

After that, Camilla will mark the bicentenary of the birth of Emily Brontë and 90 years of The Brontë Museum at The Bronte Parsonage in Haworth.
The Duchess of Cornwall will also meet volunteers restoring locomotives and travel by steam train from Haworth to Oxenhope to celebrate the 50th anniversary of the Keighley and Worth Valley Railway.
Cllr Ferman Ali, the Mayor of Calderdale, said: "It's a great honour to welcome Their Royal Highnesses to Calderdale, and excellent national recognition for the regeneration of the area.
"Our ambition for the Piece Hall transformation was to conserve the building for future generations, whilst creating a world-class tourist attraction that would strengthen the local economy. The Piece Hall and other developments in Halifax are already having major impacts, and we look forward to discussing these with Their Royal Highnesses.
"This is a really exciting time for the visit to take place, as Calderdale embarks on its next chapter to cement its place on the national and international map."
