The oldest street in town is lined with a collection of tightly packed houses and follows what was once the curving interior of Brežice's defensive walls from the castle to the water tower. It has been nicknamed Rhododendron Straße by locals in honour of the bright flowers that bloom down its entire length during the spring or early summer. While there's not any sights on the street per se, it does make for a pleasant (albeit short) stroll.
