Hello, @leaky20! Yes, actually 2-3 days before we went to Trakai, there was a swimming contest, and hundreds of people participate in it. On this photo you can see the podium for the best participants. It was made of the ice bricks they got out from the lake.
Interesting. That's really neat. 👍
I thought that the podium was a bench but that would be awful to sit on in a swim suit lol.
