In “Global History” professor of architecture Mark Jarzombek mentions medieval architect Oton Matsaetsi (Odo of Metz in Germany) who was Armenian.
Matsaetsi was the architect of Germigny-des-Pres (806-811), one of the most innovative stone structures in northern Europe.
He was also the architect of Charlemagne’s Palace Church in Aachen in 794. The church’s architecture influenced a number of other contemporary church styles.
The architect responsible, Odo of Metz, is named in a tenth-century inscription around the dome: Insignem hanc dignitatis aulam Karolus caesar Magnus institute; egregious Odo magister explevit, Metensi fotus in urbe quiescit.
