From 1000 to the early 13th century a market settlement (the future town centre) grows below the Pozsony Castle (first written reference in 1151) and becomes an important centre in the early 13th century. Further settlements in the surroundings follow. The Castle became the one with the best fortification in Hungary because of its position, it became a site of frequent attacks and battles, along with the city, and a place of frequent stay of Hungarian kings and it becomes. Around 1000 the Pozsony county (comitatus), one of the first counties in Hungary, is founded probably by Grand Prince Stephen I. Coins with the inscriptions "PHANUS REX" and "RESLAVVA CIV" were found in Sweden; some scholars claim that the coins were minted in "(p)RESLAVVA CIV(itas)" or "(b)RESLAVVA CIV(itas)" ("i.e.", in the town of Bratislava), but other authors point out that no coins of this type have been found on the territory of the Kingdom of Hungary, their weight and diameter differ from King Stephen's other coins and their inscriptions are confused which suggest that they are counterfeit coins minted abroad on the sample of other coins that had been minted following the patterns of King Stephen's coins with the inscriptions "STEPHANUS REX" and "REGIA CIVITAS".
