2.5 km91 min6 stops

What awaits you on this Red Thread tour

Look past the towering Parthenon and the modern concrete blocks, and you will find a secret city hiding in plain sight. This redthread tour takes you on an intimate journey through the Middle Byzantine period, an era when Athens was a quiet, provincial town. Discover tiny, sunken medieval churches that survived 19th-century demolition campaigns, were swallowed by modern hotels, and were built entirely from recycled ancient temples. Uncover the hidden medieval heart of the modern metropolis.
