There’s something a little disarming about these 20th century Catholic churches. The one dedicated to Saints Peter & Paul in the centre of Tuzla is no different, eliciting little in the way of excitement through its plain exterior and functional design. Look a little closer and you’ll find plenty to appreciate — the hollowed out bell tower giving its contemporary in Banja Luka a run for its money in the fascinating stakes. There is a gallery inside for any art lovers.
