Celeia, often called the “ancient city beneath Celje,” is a fascinating archaeological site that reveals the Roman roots of modern-day Celje, Slovenia. Once a thriving Roman settlement, Celeia was known as “the second Troy” for its grandeur and strategic importance. Today, visitors can step back in time and explore the well-preserved remnants of this ancient city, which lie beneath the vibrant streets of Celje’s Old Town.
The highlight of a visit to Celeia is the archaeological exhibition, where glass walkways allow you to peer down at the original Roman roads, mosaics, and marble statues that once adorned the city. Informative displays and interactive exhibits bring the daily life, art, and architecture of Roman Celeia to life, making it a rewarding experience for history buffs and curious travelers alike.
The site is seamlessly integrated into Celje’s lively town center, so you can easily combine your visit with a stroll through charming squares, medieval alleyways, and nearby attractions like Celje Castle. The city’s commitment to green tourism and heritage preservation is evident throughout, earning it the Slovenia Green Destination Gold label.
While specific opening hours and admission fees may vary, Celeia is accessible year-round and is a must-see for anyone interested in Slovenia’s rich historical tapestry. Whether you’re exploring ancient ruins or enjoying the modern city above, Celeia offers a unique window into the layers of history that define Celje.
