Style evolved in the reign of Otto the Great (Emperor 962–73), and found in Germany from mid-C10 to late-C11. The finest Ottonian Romanesque churches that survive are Ste-Gertrude, Nivelles (Nijvel), in Belgium (consecrated 1046), St Michael, Hildesheim (1010–33), and the Abbey Church of Gernrode (begun 959–63), both in Germany. The last building was apparently one of the first in Europe to have the tribune gallery. See also Carolingian, Romanesque.
