the courtyard of the Nidarosdomen cathedral in Trondheim is basically turned into a theme park during the summer months.
me and my friends were there when a guy in a medieval costume walked out on a balcony and began shouting a declaration that there would be a theatre performance.
there was also a guy pretending to be working on a block of marble, but all he had was a hammer that he limply struck the block with. no chisel, so it was all for show.
naturally, there were also a bunch of tents that sold souvenirs.
