The Isle Itself
Overview
St. Thomas Island, also known by its Bulgarian name ostrov sv. Toma or the evocative Zmiyski ostrov (Snake Island), is a distinctive Bulgarian island situated within the Black Sea. It is geographically located in Burgas Province, administered by the Primorsko Municipality. This small landmass, covering an area of approximately 0.012 square kilometers (or 3.0 acres), represents a unique ecological and historical site along the Bulgarian coastline.
Strategic Location
The island's position is notable, situated approximately 7 kilometers (4 miles) north of the coastal town of Primorsko and about 15 kilometers (9 miles) south of the historic city of Sozopol. This placement places it within a significant stretch of the Bulgarian Black Sea coast, historically important for trade and settlement.
Geographical Context
Coastal Proximity
St. Thomas Island is a prominent feature of the Bulgarian Black Sea coastline. Its precise coordinates place it at approximately 42°20′29″N 27°44′02″E. It lies a mere 0.4 kilometers (0.2 nautical miles) southeast of Humata Foreland, nestled within the waters of Arkutino Bay. This proximity to the mainland and specific coastal features underscores its role within the regional maritime landscape.
Unique Flora: The Prickly Inhabitants
An Unexpected Ecosystem
St. Thomas Island is distinguished by being one of the very few locations in Bulgaria where wild cacti thrive. Specifically, species of the Opuntia genus have established a significant presence. These cacti were not indigenous but were introduced in 1933. The initiative was spearheaded by the royal botanist Ivan Buresh, acting under the direct orders of Tsar Boris III. The cacti were sourced from the Botanical Garden in Bratislava, Slovakia, and have since proliferated, covering much of the island's surface and creating a unique botanical anomaly.
Nomenclature and Legends
Dual Identity
The island bears two primary names, each reflecting a different aspect of its identity. The name "St. Thomas Island" originates from a historical chapel once situated on the island, dedicated to Saint Thomas the Apostle. This suggests a past connection to religious or monastic life. The alternative name, "Zmiyski ostrov" (Snake Island), is derived from the abundant population of grey water snakes that inhabit the island. These snakes primarily subsist on fish found in the surrounding waters, contributing to the island's distinct ecological character.
Echoes of Antiquity: Archaeological Discoveries
Unearthing the Past
St. Thomas Island has been the subject of significant archaeological investigation, revealing layers of history dating back millennia. Initial expeditions in 1955 uncovered the remnants of a small church and associated structures, hinting at earlier ecclesiastical presence. More extensive work in 2018 yielded remarkable discoveries, including evidence of an ancient Thracian settlement from the early Iron Age, alongside Thracian ritual pits. Furthermore, findings indicate a Byzantine settlement dating from the 5th to 6th centuries AD, a small monastery from the 12th to 14th centuries, and a submerged fortress attributed to ancient Thrace, located in the waters between the island and the mainland.
A Vital Maritime Crossroads
The archaeological findings suggest that St. Thomas Island served as a crucial hub along ancient maritime routes. The National Museum of History posits that the island was the site of a significant sea route shrine. Its strategic location, directly off the ancient road connecting Sozopol (known in antiquity as Apollonia Pontica) to Constantinople (then the ancient Greek colony of Byzantium), highlights its importance as a navigational landmark and a potential center for trade and worship in the classical and medieval periods.
Protected Sanctuary
Ecological Preservation
Reflecting its unique natural and historical value, St. Thomas Island is designated as part of the Ropotamo nature reserve. This protection status aims to preserve the island's distinct ecosystem, including its unusual cactus population and the habitats of its native fauna, as well as safeguarding its significant archaeological heritage.
