Free City of Kraków
The official colors of Kraków are white and blue. The flag consists of two horizontal stripes of equal width, the top one white and the bottom one blue. The flag proportions are 5:8. The white-and-blue bicolor was adopted as the flag of the Free City of Kraków in 1815. It is almost identical with the civil flag of San Marino, the only difference being the shade of blue.
