Matthew Chapel (Matthiaskapelle) is one of the most important chapels in Rhineland-Palatinate. This chapel was built as a reliquary chapel for the safe keeping of Apostle Matthew’s head. Heinrich II of Kobern brought this relic from the Damiette crusade (1217-1221). The head was kept there for 150 years. Between 1362 and 1381, it was at castle Helffenstein. From 1422 till 1927 it was kept in the cathedral treasures of Trier. After that it was given by Nuntius Pacelli, later Pope Pius XII, to the St. Matthew abbey of Trier. The unusual ground-plan of the chapel is hexagonal and refers to oriental influences of the construction. It was built around 1220-1230.
