The excavations of the Celtic sanctuary at Sboryanovo were undertaken as a continuation of the Bulgarian-Swiss project “Sboryanovo–Necropolises and Territories” and with the financial support of the Swiss-Liechtenstein Founda- tion for Archaeological Research Abroad (SLSA). The investigations of the sanctuary – a complex of pits surrounded by ditches with a trapezoidal shape and sur were concentrated in its northern and western part. Three trenches were excavated in order to investigate and document the ditch and its structure. The ditch was originally with vertical walls. Six other trenches were also excavated in the area to the east of the sanctuary in order to study the geophysical anomalies noted in 2018. Parts of other enclosures were identified in the eastern periphery of the sanctuary. The few finds in the ditches include fragments of handbuilt and wheel thrown Thracian pottery, imported am- phorae, a glass bead and unidentified iron objects. The date of the sanctuary remains around 200 BC. The finalization of the investigations of the sanctuary – the only one of this type in present-day Bulgaria and in the Balkans – would shed important light on its character.
