The Flag of Sigmaringen is the official banner representing the German town of Sigmaringen, located in the state of Baden-Wrttemberg. The flag consists of five equal horizontal stripes in alternating colors: red and white. The design resembles the flag of the former Principality of Hohenzollern-Sigmaringen, a German princely state that existed until 1918. Today, the flag is often used to symbolize Sigmaringen's rich history and heritage.
