The Metropolitan Cathedral of Athens has a new museum that opened its doors with the presence of the President of the Hellenic Republic, Prokopios Pavlopoulos, and the Archbishop of Athens and All Greece, Hieronymus. The establishment of the Metropolitan Cathedral in 1862 was a significant moment in modern Greek history. With the help of the Stavros Niarchos Foundation, the underutilised space within the cathedral has been transformed into an exhibition area to showcase the cathedral's rich collection of religious and historical artefacts. The museum features sacred icons, original manuscripts, crosses, vestments, embroidery, and more, organised in thematic sections based on the type and function of the artefacts.

The museum's creation not only provides access to the public but also guarantees the preservation and protection of the relics for future generations. The Archdiocese, along with Archpriest Father Thomas, a long-term partner of the SNF, played a crucial role in making this museum a reality.

Also, the so-called Little Metropolis church is visible in addition to the cathedral. This smaller and older church boasts a rich history and is home to ancient religious murals that are indeed a sight to behold. Visitors are encouraged to take a moment to step inside and admire the intricate artwork that adorns the walls. This church offers a unique glimpse into the past and is a testament to the enduring cultural and spiritual heritage of Athens
