Athens Catacombs
Beneath the Church of the Holy Trinity of the Philhellenes lies a unique underground space a thousand years old. A tour that connects classical Greece, the Roman period and the deep influence of Byzantine culture.
The underground world of Athens
The Athens Catacombs lie beneath the Church of the Holy Trinity of the Philhellenes, in the heart of the city. This rare underground complex reveals a thousand years of human presence — from classical Greek roots and Roman occupation to the deep influence of Byzantine culture on the city.
These spaces are unique in Athens and largely unknown to the wider public. Every step is a journey through time.
The Church of the Holy Trinity of the Philhellenes
The Church of the Holy Trinity of the Philhellenes is one of the oldest Christian churches in modern Athens. Built in the late 19th century, its foundations contain traces of earlier places of worship and habitation dating to the Byzantine period.
The Catacombs are an integral part of the church's history, and ticket revenue directly supports its preservation.
Byzantine heritage
The Byzantine period left indelible marks on the underground space. Architectural elements, carved surfaces and construction details tell the story of a city that lived, worshipped and created beneath the surface of the earth.
Our volunteer guides bring every detail to life — from the direction of arches to the significance of carvings.
The tour experience
The visit lasts approximately 15 minutes and is led by volunteer guides from the Society. The number of visitors per tour is limited, so that each guest has a truly immersive experience.
We recommend booking your ticket online in advance to secure your place — especially on weekends.
Visiting schedules may change due to the Church's services.
