In Lithuanian Square, there is a unique object – a circular concrete structure with a screen in the middle that looks like a mirror, but in reality allows you to look into… Vilnius! At the same time, walkers in Vilnius can look into Lublin. The portal unites the two cities and is a tourist attraction that attracts the attention of people passing by. While you are there, be sure to have a look at what is happening in Vilnius and wave to the people on the other side – they will certainly wave you back!
