The old part of Kumrovec comprises the Ethnological Museum with 18 village houses, displaying permanent exhibitions of artifacts related to the life and work of Zagorje peasants in the 19th/20th century.

So far 40-odd houses and other farmstead facilities have been restored, which makes Staro Selo the most attractive place of this kind in Croatia.

According to the research of Slovenian historian Daniel Siter [sl], during the initial phase of the German occupation of the Slovene-Croatian territory between May and June 1941, the municipality of Kumrovec was temporarily occupied by Nazi Germany, along with other parts of the western outskirts of the Croatian Zagorje (Hum na Sotli, Prišlin, Druškovec, Brezno and Lupinjak).

The occupied territory of Western Croatian Zagorje (including Kumrovec) was returned to the Independent State of Croatia in mid-June 1941.

At that time, the state and occupation border between Germany and Croatia was finally established along the water line of the Sotla river.
