The Schusteröderhof, the Massing museum´s first farm, remains as it was created in 1969, a monument to the museums´s history. It boasts a fine collection of domestic utensils from the rural Rott Valley, a double balcony with hand-turned balustrade and an "Arma-Christi" crucifix on the outside wall of the barn (complete with traditional instruments).

The Kochhof is the living centre of the museum. It is "home" to peacocks, poultry, pigs, cats, a flock of pigeons and often even cattle. Every object in this farm is in its place, just as it was around 1930. Made entirely of wood, the double-balconied dwelling-house is a typical "Rott Valley Farmhouse". The barn, on which the date 1836 is painted, is constructed (on a masonry foundation) of handworked timber and boasts two threshing floor: it bears witness to the Kochhof farmer´s prosperity.

The Freilinger Häusl is presented in its original, unrestored state: thus is its history best told. It was condemned to stand empty for most of its life, or was used just as a barn. That is how this farmhouse, one of the oldest in Lower Bavaria, came to be preserved. Massive timbered construction, "Schrot" (balcony) and lapped, unnailed wooden-shingle roof - these were, for centuries, the features typifying the exterior of Lower Bavarian farmhouses.

In the Kochhof, Lehnerhof and Marxensölde, parlour, kitchen and bedchambers, cowshed, storehouses and barn are all furnished to fit the time in which the museum sets them - each farm a world "en miniature". A variety of objects - attractive and ugly, well-worn and new, long-forgotten and unchanged - tell of a bygone age.
The Marxensölde, a farm in which the dwelling also housed the livestock, has the date 1887 carved in the planks of its balcony. Everything belonging to a smallholding is gathered here under one roof.
The Lehnerhof originates from the Hallertau region: its owners earnt their livelihood by growing hops, fattening pigs and keeping dairy cattle.

The Massing Open-Air Museum is full of life. Craftsmen demonstrate their skills, festivals and markets bring music and good cheer. Gardens, fields and meadows awaken lost childhood memories, special exhibitions inform and entertain. The Spring Fair, Midsummer Festival, Harvest Beer Festival and the Museum Kirmesse on the museum´s events calender.
