Trifels Castle is a medieval castle in the Palatinate region of southwestern Germany. It is located high above the valley within the Palatinate Forest on one peak of a red sandstone mountain split into three. Emperor Henry V in 1113 made it a Reichsburg (Imperial Castle). Trifels Castle is famous as the site, where King Richard I of England (Richard the Lionheart) was imprisoned after he was captured in December 1192 on his return from the Third Crusade. Handed over to Emperor Henry VI of Hohenstaufen, a period of three weeks of captivity at Trifels from 31 March to 19 April 1193 is well documented. According to legend, Richard was found and freed by the trobador Blondel de Nesle; in fact, he was released for an enormous ransom. Trifels Castle has been gradually restored since the 19th century and today replicas of the Imperial Regalia of the Holy Roman Empire are on display here. It is one of the most popular tourist destinations in the state of Rhineland-Palatinate.
