The article describes the results of research which took place in the Etnographic Park of the Greater Poland (Western Poland), in Dziekanowice on Lednica Lake. The author has found 26 species of Aculeata (Hymenoptera) living in the wooden or clay walls and the thatched roof of the old. 18th century cottage, which used to be an inn. In keeping with present literature the author has prepared a table containing nerly 120 bee species living in old farm buildings within the area of Poland. Those species belong to 8 families: Sapygidae, Tiphidae, Vespidae, Eumenidae, Sphecidae, Halictidae, Megachilidae, Anthophoridae. The old farm buildings create a substitutive envimment for the above mentioned fauna, which normally exist in loess or clay walls, old wood or stems of green plants. Due to quick disappearing of this kind of buildings from country landscape, in 1991 some of them have been propoed to be structures protected by law — monuments of nature and architecture (Banaszak 1991, 1995). The article contains a descriptions of the first Polish monument of nature and architecture, placed in the Etnographic Park of the Greater Poland — the old, 18th century cottage which gives a shelter to rich fauna of Aculeata, (phot. 1)
