County Wicklow, Ireland
To add a layer of authenticity to the narrative, the production team of ‘Haunted Harmony Mysteries: Prelude to a Wedding’ lensed all the pivotal sequences on location in County Wicklow.

The luxurious 4-star hotel — Tulfarris Hotel & Golf Resort – Wicklow Hotel on Blessington Lakes in the neighborhood of Tulfarris — doubled as the venue for the Irish wedding where Gethsemane is hired to perform.
