“Saint Ivan” is the biggest Bulgarian island. Its highest point goes up to 33 meters above sea level. Near “Saint Ivan” is located another island – the much smaller in size island of “Saint Peter”. On “Saint Ivan” island there is a lighthouse which is 9 meters in height. It sends out sound and light signals to incoming ships in order to guide them to the port in Burgas.
The island was a sacred place for the ancient Thracians who built a sanctuary there in the VII century BCE. In the early middle ages a large monastery was built on the island, but in the year 1629 it was destroyed by forces from the Ottoman Empire. Through the years, the island has been used by pirates roaming the Black Sea.
The island is also home to a large number of bird species. On “Saint Ivan” and the nearby “Saint Peter” there are registered more than 70 types of birds. “Saint Ivan” is the home of the biggest population of the silver seagull – “Larus Argentatus”
