In 9th century Mikulčice, the central fortified area, or "Acropolis", was set on an island in the Morava and surrounded by a stone-faced rampart that enclosed an area of 6 hectares (extensive extramural settlement of 200 ha stood unfortified). Although the location of the Great Moravian capital, "Veligrad", has not been identified, Mikulčice with its palace and 12 churches is the most widely accepted candidate. An important settlement was a large agglomeration in Pohansko near Břeclav. Nitra, the centre of the eastern part of the Empire, was ruled autonomously by the heir of the dynasty as an appanage. Nitra consisted of several large fortified settlements with various functions and approximately twenty specialized craftsmen's villages, making it a real metropolis of its time. Crafts included a production of luxury goods, such as jewelry and glass. The agglomeration was surrounded by a number of smaller forts.
