Built in 1857, in our opinion this is the most beautiful train station in Poland, and neon is an integral part of the design. Wrocław Główny's renovation was completed in 2012 and included the restoration of large original neon signs on both the facade and the platforms, but the real gem is the green 'kasy biletowe kasy' neon above the ticket windows, which has been there since the 1950s. Don't miss it.
