I travel with Adrian Beasley and Paul Sanders of Lightandland to Prague in November 2019. It's a black and white workshop but I cheat a bit and I don't mind. Nice city, Prague, lots of history and good food, popular with tourists though, even in November. We walk miles and take trams.
The TESLA stained glass wall is also worth a mention. It is located at a shopping gallery off Vaclavské Námestí, the Svetozor Arcade, and dates from 1947 by Ludvik Kysela and Jan Jarolim with the Tesla sign by Frantisek Hudecek.
