Chełm

Chełm's most distinctive draw is its Chalk Tunnels — a labyrinth of underground corridors stretching some 15 kilometres beneath the city, open to visitors. Above ground, this Baroque town in eastern Poland sits on the Lublin Voivodeship's historic Ruthenian borderlands, with an Old Town centred on Castle Hill and the Basilica of the Birth of the Virgin Mary, a regional pilgrimage site. Once home to Catholic, Orthodox, Protestant, and Jewish communities, the city carries a layered multicultural past shaped by centuries at the meeting point of Polish, Ruthenian, and Jewish cultures.
