They provide the skills, time and passion that makes a remarkable place even more special.
Countryside rangers, an art ambassador, story tellers and garden guides were amongst the roles to be filled during a volunteer recruitment day at Blickling Hall.
The National Trust estate hosted more than 60 people during the event earlier this month.
Marketing and visitor manager Jo Bosch said: 'We have more than 500 volunteers at Blickling Hall and only 50 members of staff so are very much reliant on them.
'Without them we could not open the estate or carry out the conservation work we do.
'The National Trust has been trying to make volunteering easier for people doing full and part-time jobs, so the age profile is coming down and they are doing different things.'
