Guided Tour of Segóbriga and Roman Lapis Specularis Mines in Cuenca

Context The Segóbriga Archaeological Park, located in Saelices, Cuenca, preserves a remarkable Roman complex featuring a theater, amphitheater, and baths—evidence of both urban life and ancient mining activity. Just a few kilometers away, the lapis specularis mines lie hidden beneath the landscape. Lapis specularis, a natural crystallized gypsum used as window glass in Roman times, has preserved its underground tunnels almost entirely intact since the 2nd century AD. This visit offers access to a rare cultural and geological heritage site on the Meseta plateau, where mining history and urban life converge.

The Experience The tour begins with a walk through the ruins of Segóbriga, where you’ll see the well-preserved city walls and iconic structures as wind carries the scent of wild thyme. Next, you’ll travel to a nearby mine, such as La Condenada, where, equipped with helmet and flashlight, you’ll explore narrow, cool underground galleries. You’ll feel the rough texture of lapis specularis on the walls and hear the amplified echo of your footsteps in the deep chambers.

Who It’s For Ideal for families with children over six, history enthusiasts, and educational groups. Not suitable for visitors with limited mobility, claustrophobia, or children under six.

Local Context The extraction of lapis specularis was essential to the regional Roman economy, and mining traditions have deeply shaped the identity of the area. The local community continues to honor this legacy through preservation efforts at the park and mines, blending history, nature, and culture into a lasting experience.
