About Theoderic, count of Flanders

Thierry, Count of Flanders

Theoderic (Dutch: Diederik, French: Thierry, German: Dietrich;c. 1099 – January 17, 1168), commonly known as Thierry of Alsace, was the fifteenth count of Flanders from 1128 to 1168. He was the youngest son of Duke Theoderic II of Lorraine and Gertrude of Flanders (daughter of Robert I of Flanders). With a record of four campaigns in the Levant and Africa (including participation in the Second Crusade, the failed 1157–1158 siege of the Syrian city Shaizar, and the 1164 invasion of Egypt), he had a rare and distinguished record of commitment to crusading.,_Count_of_Flanders

The Basilica of the Holy Blood (Dutch: Heilig-Bloedbasiliek, French: Basilique du Saint-Sang) is a Roman Catholic minor basilica in Bruges, Belgium. Originally built in the 12th century as the chapel of the residence of the Count of Flanders, the church houses a venerated relic of the Holy Blood allegedly collected by Joseph of Arimathea and brought from the Holy Land by Thierry of Alsace, Count of Flanders. Built between 1134 and 1157, it was promoted to minor basilica in 1923.
