March 15 is 1848 Hungarian Revolution Day commemorating when the Hungarians rebelled against the Austrian attempt to kill the Hungarian language and the Hungarian culture. Szechenyi was one of the heroes of this revolution.
On this day there are Hungarian flags and colors everywhere...
even on lapels.
Anyone who has a uniform, old and young alike, seems to be wearing it.
Here you can see all the flags and the wreathes that various patriotic groups are placing at the base of Szechenyi's statue in Sopron.
