Historic Lytham Hall will be open to the public an extra two days each week from next month.
As well as offering guided tours on Sundays, the Hall is opening its doors on Thursday and Friday afternoons to guests.
During the new sessions, visitors can make their own way around the rooms on the ground and first floor, guided by a short leaflet explaining the history.
Marianne Blauboer, activity plan officer at the Hall, said: “New volunteers have been trained in the practicalities of volunteering at the Hall and given essential information about the Heritage Lottery Fund project and they will be on hand to answer any questions.”
The new opening hours come into effect on Thursday, April 3, with the Hall open from 1pm to 4pm.
