Trekanten Oslo is a new meeting place that opened on 9 September and is located in a modernist natural concrete building on St. Olavs Plass. The building, designed by the architect Erling Viksjø, was built between 1968 and 1969 for Oslo Health Council. The ground floor has been transformed into a publicly accessible area that includes a café, bar, restaurant and a monumental stage space. This makes the Triangle a significant addition to the Tullin area.
The venue offers flexible function rooms suitable for various events, including courses, meetings, wedding parties and Christmas parties. With modern facilities and customized solutions, Triangle is well suited for both private and corporate events. It is also ideal for summer parties and kick-offs. Guests can stay up-to-date on activities and events through newsletters. The triangle aims to be an arena for experiences in music, literature, film, design, fashion, architecture and art.
