Heybeliada or Heybeli Ada (Greek, Χάλκη, Chalki) is the second largest island of the Prince Islands, located in the Sea of Marmara. It is a district of the Adalar district in Istanbul, Turkey. Places of interest There are two architectural elements of interest on the island, on the grounds of the naval school: Kamariotissa, the only Byzantine church remaining on the island and the last church to be built before the conquest of Constantinople; and the tomb of the second English ambassador who sent Elizabeth I of England, Edward Barton, to Constantinople, who decided to live in Heybeliada fleeing the busy city life.
At the top of the central hill is an 11th-century Orthodox monastery, home to the Halki seminary (Turkey's main Orthodox seminary and theological seminary of the Ecumenical Patriarchate of Constantinople.) The monastery attracts numerous tourists from Greece and Turkey. Demography
The population in winter is about 3,000 people, although in summer the owners of summer houses return and the population increases up to 10,000. Transport
In order to avoid contamination, motorized vehicles (with the exception of service vehicles) are not allowed, so visitors can travel by foot, bicycle or horse carriage. There is no airport, so the only access is by boat.
