Płock

Płock, the capital of Poland from 1079 to 1138 and the seat of Masovia since 1138, is a ducal castle on the high Vistula bank (the Cathedral Hill, Wzgórze Tumskie) with the cathedral of the Virgin, completed under Bishop Alexander of Malonne in 1144, the bishop's court and the Benedictine abbey of St Adalbert.

Below and beside them lies a market settlement of craftsmen, fishermen and traders where the Vistula road meets the routes to Rus' and to the Prussian lands. A school is said to have opened here in 1180 (de.wikipedia; a traditional date). In 1200 it has no town law and no council; German town law comes about 1226 or in 1237 (de.wikipedia), renewed in 1255.
