The We Are Singing Ljubljana choral festival will bring international choirs to Postojna Cave (Postojnska jama) in Postojna on 17 October 2026. The programme places the gala concert inside one of Slovenia's best-known underground venues during the festival's 16 to 18 October run.
The event gives the cave a current cultural role beyond its regular visitor programme. The organisers describe a concert of choral music ranging from the Renaissance to contemporary works, with singers from choirs around the world.
We Are Singing Ljubljana brings choral music underground
The festival's official programme lists Ljubljana and Postojna Cave as its two venues. The opening festival activities are scheduled for 16 October 2026, while the Postojna programme is set for the following day.
According to the festival programme for 17 October, participants meet at the cave at 2.30pm. A cave tour is planned before the concert, followed by the gala concert at 5pm and a final song at 6pm. The organiser notes that the listed times are approximate and may change.
The organiser's broader festival page describes the 17 October performance as a public concert. It identifies the programme as an international choral festival and places the Grand Concert at Postojna Cave.
Postojna Cave's Grand Hall has a concert history
The setting is part of the attraction's established cultural history. Culture.si, a portal maintained by Slovenia's Ministry of Culture, records that the cave system extends for 20,570 metres and that 5.3 kilometres are open to the public.
The same Ministry of Culture profile says the Grand Hall can receive up to 10,000 visitors and has often served as a concert venue. Its acoustics and unusual underground setting therefore connect directly with the festival's choral programme on 17 October 2026.
The cave's public history reaches back to the early nineteenth century. After Luka C?ec? discovered new sections in 1818, it opened to visitors in 1819. A tourist railway was added in the 1870s, followed by electric lighting in 1884.
Those changes help explain why a choral concert can form part of a visit rather than stand apart from the site. Visitors encounter a show cave shaped by scientific exploration, engineered access and a long tradition of public performances.
