Winster Market House was the first property to be acquired by the National Trust in the Peak District in 1906, for £50.
It is a lovely brick built listed building and is now an information room with interpretation panels and a scale model of Winster village.
Admission is free, and the building is usually open during daylight hours.
The National Trust do not have a separate page describing the Market House, but it is briefly mentioned as part of their White Peak information page
