The Hohenzollern Castle series issued by the Republic of the Congo belongs to a wave of European landmark coins produced under licensing arrangements that flooded the numismatic market in the early 2000s. The Congo — specifically the Republic of the Congo, not the Democratic Republic — became a particularly active issuer of these collector-targeted pieces, having little connection to the subjects depicted beyond the minting agreements themselves. The original Hohenzollern Castle in Baden-Württemberg was rebuilt in its current form between 1846 and 1867 under Prussian Crown Prince Friedrich Wilhelm, on the ruins of two earlier fortresses.
