Kostrevniška dolina
The villages of Mala Kostrevnica, Velika Kostrevnica, Dvor and Lupinica are located in the Kostrevnica Valley. Meadows and fields surround the stream Kostrevniški potok, sometimes closing in and then dispersing into mixed forests. The location name Kostrevnica (Cozdruniz) was first mentioned in 1136. The second written reference dates to 1169. That was when Burkard von Pouch from Podbukovje pri Vačah donated the “Cozruidniz castle” to the monastery in Stična. The name of the village is of Slavic origin – kostreva, meaning a variety of grass, probably the rye brome (Bromus secalinus). The beautiful meadows of Kostrevnica are also mentioned by Johann Weichard Freiherr von Valvasor (Slovene Janez Vajkard Valvasor) in his Glory of the Duchy of Carniola.

Dam at Blaj (Slovene Jez pri Blaju)
According to Valvasor, a great dam was once built between hills below the mill, retaining a lake of water all across the Bajernik Valley. Such an arrangement was due to the enemies, most likely Turks. If the Turks attacked, they would open the dam, flooding the enemy troops.
Double Hayracks (toplars)
There are still some double hayracks or toplars preserved in the valley, masterpieces of native architecture; the Olafov double hayrack is situated by the road in Mala Kostrevnica, while the Mačkov double hayrack is in Velika Kostrevnica.
The chapel
The chapel in the village centre was built in gratitude for the safe return of the boys and men from World War I.
