Church in Russe, Bulgaria. Russe is a neat little town at the border with Romania. It is linked to the Romanian town Giurgiu by a bridge over the Danube. The bridge is shared by both countries, the border being somewhere in the middle of it. There are some cool caves worth visiting nearby Russe, so you might want to go on a one day trip from Bucharest, should you happen to be around some time during the summer.
