This sundial is on the south wall of St. Mary’s Basilica of Krakow (also known as Church of Our Lady Assumed into Heaven).
This 14th-century church is famous because on every hour the Hejnal mariacki is played from the top of its highest tower. The song breaks doesn’t finish to commemorate the death of trumpeter who was shot in the throat while sounding the alarm before the Mongol attack on the city.

This doodle was published last year to commemorate Grace Hopper’s 107th Birthday. Hopper (December 9, 1906 – January 1, 1992) was an American computer scientist who first developed the first compiler for a computer programming language. Her ideas led to development of COBOL programming language.
She was buried in Arlington National Cemetery.
In the ground floor of the Cloth Hall of Krakow there is this modern plaque (2007) designed by Czeslaw Dźwigaj and the selection of the text was made by Jerzy Wyrozumski and Alexander Kravchuk:
1257 Krakow city rights advocates by the German tradition and the situation of the market and the houses and affected courts
It was Bolesław V, “the Chaste One”, (1226–1279), Duke of Sandomierz in Lesser Poland from 1232 and High Duke of Poland from 1243 until his death, who introduced in 1257 the city rights modelled on the Magdeburg law allowing for tax benefits and new trade privileges for the citizens and this plaque was designed to conmemmorate the 750th anniversary of this moment.
The Cloth Hall is one of the most emblematic symbols of Krakow because is probably the oldest shopping mall in the World:
It’s in the middle of the main square of Krakow and everybody visit it and buy something in the shops of the ground floor.
So next time that you visit Krakow look at the floor to this conmemorative plaque:
