The Trinity Hill is the oldest surviving district of Minsk, although it's not part of the downtown, rather a suburb, hence another name, Trinity Banlieu (Trojeckaje Pradmiescie). The historic neighbourhood sprawls along the left bank of the Svislach River in the southeastern part of the modern city. The Belarusian 5-ruble bill features an image of Trayetskaye Pradmestsye. The district takes its name from the Trinity Convent, of which little remains. The first Roman Catholic church in Minsk, the Ascension Monastery, the church of Sts. Boris and Gleb, and a synagogue have also disappeared. This is an area of 19th-century housing, mostly restored after the ravages of World War II. Modern buildings include the national opera and ballet theatre and the Island of Tears memorial.
