The Underground Main Square Museum, or Rynek Underground, is one of Kraków’s most remarkable and must-see attractions. Situated directly beneath the bustling Main Market Square, it offers visitors a chance to explore the city’s rich history in a unique subterranean setting. Covering around 4,000 square metres, the museum opened to the public in September 2010, following a major project that began in 2009. Its central theme, “Tracing Kraków’s European Identity,” presents an immersive journey into the city’s past, revealing the layers of history that lie hidden beneath the cobblestones of the Old Town.

The museum’s flagship exhibit employs cutting-edge multimedia techniques to bring Kraków’s medieval history to life. Using holographic projections, fog effects, and interactive screens, visitors are transported back nearly seven centuries to the bustling streets, markets, and homes of the city. Among the fascinating objects on display is the notable 693-kilogram medieval lead artifact known as the “loaf,” alongside everyday relics such as coins, statuettes, tools, games, and weaponry. An interactive catalog with 3D models allows guests to examine these artifacts in detail, making the history both tangible and engaging.

Beyond the multimedia displays, the museum explores the city’s medieval infrastructure and underground passages. Transparent walkways give visitors a rare perspective on the subterranean network of streets, workshops, and storage areas that once existed beneath Kraków. This part of the museum reveals remnants of architectural and civic innovations, including the reconstructed 12th-century workshop, traces of ancient aqueducts, and scorched remains of settlements from the 11th century. Each feature tells a story of the city’s evolution, connecting modern visitors with the people who shaped Kraków long ago.

The museum also brings to life the commercial heartbeat of medieval Kraków. A carefully recreated merchant’s stall allows guests to experience the sights and activities of a medieval marketplace, while maps of historical trade routes highlight the city’s role as a hub of European commerce. These exhibits demonstrate how trade, craftsmanship, and cultural exchange contributed to Kraków’s growth and significance over the centuries, emphasizing its enduring influence in the region.

Visiting the Rynek Underground Museum offers more than just a glimpse into the past—it is a full sensory experience that blends history, technology, and storytelling. By walking through the reconstructed passages, examining the artifacts, and engaging with the interactive displays, visitors gain a deep appreciation for the complex layers of Kraków’s history. The museum is both educational and captivating, making it an essential stop for anyone exploring the Old Town and wanting to uncover the hidden stories beneath one of Europe’s most beautiful squares.
