St. Sofia Church

St. Sofia Church, one of the oldest churches in the Bulgarian capital, traces its core structure back to the sixth century, though it has undergone significant changes over the centuries. Located in Sofia, the site is a testament to layers of history, with excavations revealing the remains of several earlier churches and a Roman-era necropolis beneath and around the Byzantine basilica. Today, visitors can explore an underground museum that showcases these archaeological findings, offering a glimpse into the rich and complex past of this enduring religious site.
