The 17th edition of the Open House Festival is here

Under the theme All Measures of Architecture, this year’s edition highlights how architecture connects heritage, culture, infrastructure and contemporary living, offering a unique insight into the country’s built environment.

Cultural, Historical and Exhibition Spaces

A strong focus is placed on Slovenia’s cultural and historical heritage, with access to sites such as Novi trg and Lontovž, Plečnik in Kranj, the Palace of the City Municipality Kranj, Plečnik’s Palace – Constitutional Court, as well as Plečnik’s House and Plečnik’s Insurance Building.

Visitors can also explore monastic and historic complexes, including the Hidden Corners of the Former Cistercian Monastery Kostanjevica na Krki and the Franciscan Monastery of Kostanjevica in Nova Gorica, alongside contemporary interpretations like EPICenter – City on the Border and the parchment exhibition.

Among the highlights are major cultural institutions and renovation projects: Cukrarna Palace, Maribor Art Gallery, the Pilon Gallery Ajdovščina Renovation Project, and the Permanent Exhibition in the Tone Pavček Museum.

Heritage restoration is further showcased through the restoration of Štanjel Castle, the renovation of the outbuilding at the Prešeren homestead in Vrba, the renovation of the Vodnik Homestead, and the former Auersperg ironworks at Dvor near Žužemberk.

Additional architectural landmarks include Gruber Palace, Muza – Museum, Gallery and Academy, the Pelikan Photo House and the World’s Oldest Vine House Renovation.

Infrastructure, Public Space and Contemporary Interventions

The festival also opens doors to large-scale infrastructure and public projects shaping Slovenia’s future. These include the construction site of the New Ljubljana Railway Station, offering a rare behind-the-scenes look at one of the country’s key transport developments, and the Karavanke Tunnel – second tube, an important cross-border infrastructure upgrade.

Public and landscape architecture is represented by projects such as the Ribnica Urban Centre, the Vevče Swimming Pool Complex, and the Tolmin Gorges Entrance Point, highlighting how design enhances public space and visitor experience.

Tourism, Hospitality and Experiential Architecture

Tourism-oriented architecture plays a key role in the programme, showcasing how design shapes memorable experiences in nature and beyond. Featured projects include the Julian Alps Hotel, Glamping Camp Danica, and the Local Community Centre Hotel in Čezsoča.

Visitors can also explore Wellness Vodian, the Winery Trifolium in Goriška Brda, and the Doppler Estate, where architecture meets landscape, gastronomy and well-being.

Together, these and many other projects reflect Slovenia’s architectural diversity – from historic monasteries and cultural institutions to cutting-edge infrastructure and sustainable tourism design. Through guided tours led by architects and experts, the festival offers a rare opportunity to experience spaces not just as observers, but as active participants.

Registration for guided tours opens on 8 April.
