Kaunas GeoFortress 2025

The theme of the first international GeoFortress event in Lithuania is the heritage of military architecture in Kaunas. Geocachers from all over Europe can enjoy not only historical sites, but also beautiful natural views, as most military structures are surrounded by nature or offer a great panoramic view of the city's surroundings. This event is expected to attract not only military history and architectural heritage enthusiasts, but also anyone looking for unique and memorable experiences during the event.

Kaunas, the second-largest city in Lithuania, has an international airport and a rich history. In the interwar period, it served as Lithuania’s temporary capital, fostering a network of scientific and cultural institutions. In 2022, Kaunas held the prestigious title of European Capital of Culture, and in 2023, its modernist architecture was recognized by UNESCO as part of our shared heritage.

But there’s more to Kaunas than the famous titles. Nestled at the confluence of Lithuania’s two largest rivers, Nemunas and Neris, the city has always played a significant role in strategic defense. During the reign of the Russian Empire, there were plans to transform Kaunas into a major fortress. While this slowed down urban development, today, the remains of those fortifications stand as iconic landmarks.

From 1882 to 1915, Kaunas witnessed the construction of 250 military structures, including churches, forts, administrative buildings, tunnels, warehouses, and water towers. Kaunas Fortress remains one of the best preserved examples of military engineering in Eastern and Central Europe. Its defensive installations continue to awe visitors with their underground passages, well-designed water systems, and historical significance.

The fortress, characterized by its distinctive red-brick architecture, now houses educational, recreational, and cultural activities. Museums, university departments, residential buildings, public institutions, Lithuanian military units, and even industrial enterprises occupy parts of this historic complex. Notably, the nine forts in and around Kaunas have been adapted for educational tourism.
