Summer events in the Metlika Castle started in 1982. In the beginning, they organised „Noči do jutra“ (Nights till Morning) and „Avgustovska noč“ (The Night in August), „Pridi zvečr v grad“ (Come to the Castle in the Evening), and since 1993, „Pridi zvêčer na grad“ (Come to the Castle Tonight).
These events, also known as Metliško kulturno poletje (Metlika Cultural Summer), are intended for all age groups and have an international dimension. The event presents a high-quality programme with top domestic and foreign performers, which is clearly shown by a growing number of visitors. In addition to performances (stage plays, concerts, monocomedies, interviews, poetry …), it is taken care also of children by free movies in Kulturni dom Metlika (Cultural Centre Metlika).
