This unique walking experience moves swiftly through Sofia's archaeological and historical heart. We then trade the dense urban core for a green refuge as we enter Boris’ Garden, known affectionately as 'The Lungs of Sofia', where nature meets national heritage.
The adventure culminates with exclusive access to the University Astronomical Observatory, one of the oldest astronomical institutions in the Balkans. You will receive a rare guided tour of this pioneering scientific complex, encountering historic instruments like the still-functional 15.2cm Grubb Refractor. If the weather allows, you will have the extraordinary opportunity to look into the night sky through an original telescope, connecting directly with the stars that inspired Bulgaria's first modern scientists.
This is the perfect tour for the intellectual traveler, offering a deep dive into history, nature, and the cosmos in a powerful, high-value, 4-hour sprint.

What To Expect
Begin your tour at Saint Nedelya Church, one of Sofia’s most historic landmarks. Here you’ll uncover the story behind the 1925 terrorist bombing, one of the most dramatic events in Europe’s interwar history. This powerful introduction sets the stage for your journey through the era of the Bulgarian monarchy (1879–1944)—a period marked by royal ambition, political intrigue, and national transformation. It’s the perfect starting point for understanding how Sofia became the capital it is today.
Continue your journey at the Ancient Serdica Archaeological Complex, where Sofia’s Roman past comes to life beneath the modern city. Here you’ll walk through the remains of streets, homes, early Christian basilicas, and fortress walls that once formed the thriving Roman town of Serdica, so beloved that Emperor Constantine reportedly considered making it his capital. This stop reveals how Sofia has grown layer by layer over the centuries, blending ancient foundations with today’s vibrant urban heart.

5.00I had a great experience on the Sofia Highlights Walking Tour with a Visit to the Old Observatory. Our guide, Lyubo, was very knowledgeable and shared fascinating stories about the city’s history as we walked through key landmarks like Saint Nedelya Cathedral, the Ancient Serdica complex, the Rotunda Church of St. George, and the impressive Alexander Nevsky Cathedral. I especially enjoyed learning how Sofia - once known as Serdica - evolved through Roman, Byzantine, and Ottoman periods. The walk through Sofia University and Borisova Gradina Park was also lovely in the evening. The highlight was the visit to the Astronomical Observatory at Sofia University. Ending the tour by observing Jupiter through the telescope was a memorable experience. A perfect mix of history, culture, and science - highly recommended! Thanks to Adrian for organising the tour...
