The Museum of the Countryside in Sierpcwikipedia:
It is an open-air museum and is located in the suburbs of Sierpc in the valley of the Sierpienica River and its confluence with the Skrwa River. Though it looks like a separate and independent village because of its great area (about 60.5 hectares) and due to the fact that it is fenced, the museum is included within the town's borders. The village is made up of 11 farms (houses - cabins, barns, cowsheds, granaries, pigsties), an inn, a blacksmith's workshop, an oil - mill, a windmill and a small chapel. Everything was collected from different regions of Masovia. The architecture of houses reminds that from 19th or early 20th century. Also inside the houses there are pieces of furniture, utensils, equipment and hand-made decorations which are appropriate to the epoch. Each season there are exhibitions devoted to traditional Masovian customs i.e. "Christmas in Mazovie Region", "Easter in Mazovie Region". Also children can find something interesting for them : "Palm Sunday in Skansen museum", "Sunday in Skansen museum", "Cooking in the middle of the glade", "Children's Day in Skansen museum", "Honey harvest in Skansen museum" or "Harvest season in Skansen museum".
