Saturday morning, with my brother Philippe, we visited part of Kraków, starting with the Wawel Castle, that has been the residence of the kings of Poland for centuries.
Wawel Castle
At one of the entrance of the castle, there is an equestrian statue of Tadeusz Kościuszko who "was a Polish-Lithuanian military engineer, statesman, and military leader who became a national hero in Poland, Lithuania, Belarus, and the United States", as he fought "on the U.S. side in the American Revolutionary War." (Wikipedia)

Like in the Prague castle, inside the Wawel castle there is a cathedral: the "Royal Archcathedral Basilica of Saints Stanislaus and Wenceslaus", known simply as the Wawel Cathedral,

Inside the main courtyard of the case, we admired this magnificent ivy bush, 7 to 8 m high, that must be very old

After the visit of the castle, we went to the "Art at SteemFest" display. We were a little disappointed because the artworks were not printed but simply projected on the four walls of the room and constantly rotating.
However, as we are nerds, we were amazed that we could not see any discontinuity on the images from the ten video projectors.

We continued our visit through the Jewish quarter, before going back to the hotel.

In the afternoon, I went to the boat tour on the Vistula river with many Steemians.

And that was it for me for the day. I did not participate to Beer Saturday, that apparently was enjoyable, or to the SteemFest Karaoke.
