Maria Laach Abbey

Maria Laach Abbey (in German: Abtei Maria Laach, in Latin: Abbatia Maria Lacensis or Abbatia Maria ad Lacum) is a Benedictine abbey situated on the southwestern shore of the Laacher See (Lake Laach), near Andernach, in the Eifel region of the Rhineland-Palatinate in Germany. It is a member of the Beuronese Congregation within the Benedictine Confederation. The abbey was known for nearly 770 years as "Abtei Laach" ("Abbatia Lacensis" or "Laach Abbey", meaning the "Lake Abbey") until 1862 when the Jesuits added the name "Maria".

Founded in 1093 as a priory of Affligem Abbey (in modern Belgium) by the first Count Palatine of the Rhine Heinrich II von Laach and his wife Adelheid von Orlamünde-Weimar, widow of Hermann II of Lotharingia, Laach became an independent house in 1127, under its first abbot, Gilbert. Affligem itself had been founded by Hermann. Although the abbey was founded by a prominent (although perennially excommunicated) member of the imperial party (Investiture Controversy), Affligem became soon after a prominent member of the Cluniac reform movement.

The abbey developed as a centre of study during the 12th century. The 13th-century abbots Albert (1199–1217) and Theoderich II (1256–1295) added significantly to the buildings and architectural decoration, including the monumental tomb of the founder.
