The document of Premysl I - the duke of Poznan, dated from 1247, provides information that in the mid-13th century in the fortified settlement of Poznan, next to the church of the Holiest Virgin Mary, there was a throne, on which the ruler sat while ceremoniously passing a legal act. The event took place on the isle of Ostrów Tumski in Poznan, in the western part of the Piast stronghold where there stood a church dedicated to the Holiest Virgin Mary - a successor of an early-Piast palace chapel, most likely founded in the 60s/70s of the 10th century by Duchess Dabrówka (Dubrava), the first Christian wife of Duke Mieszko I. Most probably, it was a massive, nonportable stone throne located in open air, in a visible place, on the hillock occupied, among others, by the church of Virgin Mary, most likely near the south wall of the temple. In this context, attention is attracted by a stone threshold of the north portal of the Gothic church of the Holiest Virgin Mary on Ostrów Tumski in Poznan - a massive granite block, which had been inbuilt there again, with visibly shaped seat on the inner surface, resembling, as far as its form is concerned, its primitive finishing and dimensions, the throne stones from Scandinavia and the British Isles. It shares close similarity with a granite block currently situated inside the early-Piast palace chapel of the stronghold on Ostrów Lednicki, which Jan Lesny interpreted in a convincing manner as an element of a stone throne from the times of the first Piasts. Furthermore, a legend is connected with Lednica about a gold regal throne on the stronghold's isle, which became flooded, along with other treasures, in the waters of the local lake.
