Milyon Taşı - Free Audio Guide

Milyon Taşı (Milion) is a Byzantine-era milestone in Istanbul, first erected in the early 4th century under Constantine I as the ceremonial zero point from which distances across the Eastern Roman (Byzantine) Empire were measured. Situated near Hagia Sophia and the former Hippodrome in the Sultanahmet quarter, it served both practical and symbolic purposes within imperial administration and public processions. Only fragmentary remains survive today, embedded in the historic urban fabric and examined by historians and archaeologists as testimony to Constantinople’s infrastructure and imperial identity. The monument’s cultural importance derives from its association with the capital’s centrality and the medieval road network. The remains are visible in the Sultanahmet area; visiting hours and admission arrangements vary with local management and neighbouring museum schedules. Accessibility is variable: the remnants lie in an open, uneven setting and on-site facilities may be limited.
