Priest Cezary Korzec stands in front of his house in the village of Rosow, Germany, located near the Polish border April 7, 2013. When Poland joined the European Union a decade ago, people in the Polish border city of Szczecin expected their neighbours in Germany to move in with their bulging wallets and buy up Polish houses and businesses. But events took an unexpected turn. Large numbers of well-to-do Poles from Szceczin are moving into Germany and buying properties on such a scale that sleepy Prussian villages are taking on a Polish air. Korzec, a Polish Catholic priest who lives in Rosow, said that in the parish to which the village belongs, the number of practising Catholics had gone from 1,200 to 1,800 in the past few years because of the influx of Poles.
