Zagreb's 'Sokolska Mogila' Time Capsule Opening Delayed Again

A time capsule, sealed within Zagreb's "Sokolska mogila" in 1926, holds a collection of artifacts from Croatia's early 20th-century history and culture, yet its opening remains elusive. The structure, designed by architect Aleksandar Freudenreich, was erected to commemorate the thousandth anniversary of King Tomislav's coronation.

The capsule's unveiling, initially slated for last year as part of the 1100th anniversary of the Croatian Kingdom, has encountered persistent delays. The "Brothers of the Croatian Dragon" Society, the initiative's driving force, confirmed they have not abandoned the project but cited a lack of organizational and other resources as the reason for the stalled preparatory activities.

The "Brothers of the Croatian Dragon" Society has not abandoned the project, but unfortunately, due to a lack of organizational and other resources, it has not been possible to initiate preparatory activities. We will inform you as soon as there are any developments.

Previous discussions with Zagreb city officials and the planned formation of a multi-institutional working group had suggested progress. This group was intended to bring together relevant experts to facilitate the complex and costly endeavor. However, these plans have not materialized, and the project has effectively returned to its starting point.

Items within the capsule are believed to include books, newspapers, magazines, and commemorative records from various Croatian Sokol societies that participated in the mogila's construction. Historians and conservators anticipate that its opening could reveal valuable materials unseen for decades, offering a unique glimpse into Croatia's past.

Given that this is a very complex and expensive project, a working group will be formed comprising representatives from multiple institutions so that relevant experts can contribute and help in the quality realization of the project. The opening of the mogila is unlikely to happen before the end of this year, and spring 2026 is more likely.
