Chełm

The city is of mostly industrial character, though it also features numerous notable historical monuments and tourist attractions in the Old Town. Chełm is a multiple (former) bishopric. In the third quarter of the 13th century, it was the capital of the Kingdom of Galicia–Volhynia. Following the Galicia–Volhynia Wars of succession, in the mid-14th century, the town became part of the Kingdom of Poland. Chełm was once a multicultural and religious centre populated by Catholics, Eastern Orthodox Christians, Protestants and Jews. The Jewish population was decimated in World War II, going from 15,000 Jewish inhabitants to mere dozens. From 1975 to 1998 it was the capital of the Chełm Voivodeship. The city's landmarks are the Castle Hill with the Basilica of the Birth of the Virgin Mary and the unique Chełm Chalk Tunnels spanning some 15 kilometres (9 mi) of underground routes.
