Following the Hungarian conquest of the Carpathian Basin at the turn of the 9th and 10th centuries , Prince Árpád gave Komárom and the Komárom county vicinity to tribal chieftain Ketel . Ketel was the first known ancestor of the famous Koppán ( genus ) clan . At the beginning of the 12th century , this tribe founded the town 's Benedictine Monastery in honor of the Blessed Virgin , mentioned in 1222 by the name of Monostorium de Koppán . The Turks destroyed much of the monastery and its surroundings in 1529 , and the area was thus depopulated . Later references refer to it as the Pioneer Monastery ( Pusztamonostor ) . Presently , it is called Koppánymonostor ( Koppán 's Monastery ) in honor of its founding family . Roman ruins ( including a stone mile marker and watchtowers ) still stand today . The town was heavily damaged in the 1763 Komárom earthquake
