The tunnel network was excavated using primarily manual labor, carved directly into the rhyolite tuff bedrock.
The system was used to store tithes, specifically wine, which were collected from the surrounding Eger wine region.
The total length of the interconnected tunnels reaches approximately 4 kilometers beneath the city center.
The tunnels were instrumental in stabilizing the ground beneath the Eger Cathedral.
The subterranean humidity and steady temperature were ideal for preserving the quality of stored wine for decades.
The City Under The City, known locally as Város a város alatt, is a multi-level subterranean tunnel system carved directly into volcanic tuff beneath Eger. Originally constructed as a cellar network for the Eger Cathedral Chapter in the 18th century, the tunnels span approximately four kilometers. The excavation utilized local rhyolite tuff, a soft volcanic rock that hardens upon exposure to air. The system served as a primary storage facility for tithes collected in wine during the Ottoman occupation and post-liberation periods. Parts of the tunnels were interconnected to provide structural support for the foundations of the Basilica and the Lyceum above. Visitors explore a designated exhibition route that highlights the history of the region's viticulture and bishopric administration. The tunnels maintain a consistent, cool microclimate year-round due to their depth and stone construction. It remains one of the most extensive historical cellar systems in Central Europe.
The main intersection where the vaulted ceilings meet and the light hits the texture of the carved rhyolite walls.
Wear a light jacket or sweater, as the temperature inside remains significantly cooler than the surface, regardless of the season.
Wear sturdy, closed-toe walking shoes as the floors can be uneven and occasionally damp.
Check for guided tour availability in your language before arrival, as self-guided access is often restricted.
Do not attempt to stray from the marked visitor paths, as the network is vast and contains many restricted or unreinforced sections.
Occasionally closed during local winter months or for private maintenance; always verify operational status for the specific week of travel.
Maintain a quiet volume as sound carries significantly through the stone tunnels.
