Saint Mary’s Basilica is a Brick Gothic church adjacent to the Main Market Square in Kraków, Poland. The interior is beautiful and well worth the 15zł (€3.20) ‘donation’ to enter.
On every hour, 24 hours a day, 365 days a year, a bugle call, called the Hejnał mariacki, is played from the top of the taller of Saint Mary’s two towers.
The call was originally used to warn that the city was under attack. In 1241, a Mongol army arrived at the gates and the bugler began to play, only to be shot by an arrow midway through the call.
These days, the call breaks in mid-note, to commemorate the bugler who died saving the city.
