The Manx Museum will stay open on a Sunday.
That’s according to Manx National Heritage which says it will be asking Tynwald to approve the change.
Director Edmund Southworth says: “When MNH prepared its business case for trialling Sunday openings it identified a number of criteria against which success would be measured.
“After almost nine months of operation it is clear that the trial has been a success.
“Research findings include 66 per cent of visitors saying they combined their visit with an event, shopping or eating out in Douglas, indicating a positive contribution to the local economy.
“Audiences have been broadened too and there are also a greater proportion of local residents visiting on Sundays with people citing that it is the most convenient day for them to visit.”
If approved revised opening hours will be applicable from April 1st 2019.
