Located in the renovated former municipal office, Postojna Culture House opened its doors in 2001 offering a cultural programme of music and theatre performances by groups from Slovenia and neighbouring countries, including a concert subscription series for local audiences as well as film screenings, workshops and exhibitions.
Since March 2016 the municipal public institution is one of five units of the Zavod Znanje Postojna (Knowledge Postojna Public Institution).
There is also a memorial room dedicated to local writer Alojz Kraigher (1877–1959) which can be visited by appointment with the Notranjska Museum, Postojna.
The main hall with its 100 square-metre stage has 288 seats, while an adjacent room for seminars or parties can host up to 60 people. Both rooms are available for hire.
