ÓZD
Origin/meaning:
The left arms are those from the communist-socialist era of the city Ozd, the red star is a communist symbol, the three grey things are representing the iron factory, which used to be the main employer in the city. Red and blue are iron manufacturer colours in Hungary.
The right arms were created after socialism was over. The three hills can be in connection with Hungary's flag (three famous mountains in the past) or that city is between hills, the small building is representing that iron manufacturing is very important in Ozd and in this region (the building is a very old iron manufactory), the other symbols indicate that agriculture is also common here.
