Welcome to Sofia, the capital of Bulgaria and one of Europe's oldest continuously inhabited cities. I'm delighted you'll be joining me as we explore a place where nearly every street reveals another chapter of a story that stretches back more than 7,000 years. Today, we'll walk through the very heart of the city, discovering magnificent churches and grand public buildings, ancient Roman streets, peaceful parks, lively squares, and some of Bulgaria's most important cultural and political landmarks. Along the way, you'll learn how Sofia has been shaped by Thracians, Romans, Byzantines, Bulgarians, Ottomans, and many others who have called this remarkable city home. Before we begin, let's talk about the city's name. Long before it became Sofia, this city was known as Serdica, named after the Serdi, a Thracian tribe that settled here centuries before the Romans arrived. When the Romans conquered the region in the 1st century AD, Serdica grew into one of the empire's most prosperous cities. Its location at the crossroads of important trade routes made it a thriving center of commerce, culture, and government. The city became so important that the Roman Emperor Constantine the Great is said to have declared, "Serdica is my Rome." According to tradition, he even considered making it the capital of the Roman Empire before ultimately choosing Byzantium, the city that would later become Constantinople. The name Sofia didn't appear until much later. It comes from the nearby Church of Saint Sofia, one of the oldest buildings in the city. Interestingly, the name doesn't refer to a woman named Sofia. Instead, it comes from the Greek word Sophia, meaning wisdom, and specifically refers to Holy Wisdom, an important concept in early Christianity. Over time, the church became such a prominent landmark that people gradually began referring to the entire city by its name. As you'll soon discover, Sofia is a city of fascinating contrasts. Ancient Roman ruins lie beneath modern streets. Ottoman architecture stands just steps from Orthodox cathedrals. Communist-era government buildings share the skyline with elegant palaces and lively pedestrian boulevards. Somehow, all these different periods of history come together to create a city that feels both timeless and unmistakably modern. A few quick tips before we set off. Please stay aware of your surroundings, especially when crossing streets, and always use designated crosswalks or pedestrian underpasses when directed. If you'd like to spend extra time exploring a church, museum, or landmark, simply pause the tour and resume whenever you're ready. This is your journey, so take it at your own pace. Now, if you're ready, let's begin our walk through one of Europe's most underrated capitals and uncover the remarkable stories that have shaped Sofia for thousands of years.
