On every hour, a trumpet signal - called the hejnał (pronounced hey-now) - is played from the top of the taller of St. Mary's two towers. The plaintive tune breaks off in mid-stream, to commemorate the famous 13th century trumpeter, who was shot in the throat while sounding the alarm before the Mongol attack on the city.You can listen to the trumpet here.
Here are my pictures of the basilica in the daytime and in the nighttime.
The basilica sits on the northeast corner of Krakow's Market Square. For many centuries it was the largest marketplace and town square in Europe. In the center of the square is Cloth Hall. Here's my picture of Cloth Hall.
Also in the square is the Town Hall Tower, built in the 13th century. Here are my pictures of the tower in the daytime and in the nighttime.
