Ritlite is a natural attraction, part of the territory of the “Vrachanski Balkan” Natural Park, located on the rocky slope above the Lyutibrod village, on the left bank of the Iskar River. This wonderful work of nature consists of four almost parallel vertical walls, with a length between 200 and 500 meters and a thickness between 3-7 meters. The rock isformed 120 million years ago from durable limestone, from the deposits on the seabed that covered these areas and formed by folding the Alps-Himalayan mountain range. Similar formations exist on the opposite side of the river, but they are smaller in size. Legend has it that long ago there was a massive iron door that closed the path to the old Bulgarian city of Serdika. The objective derives its name from the fact that arrangement of the rocks looks like the side walls of a cart drawn by ritli oxen. Since 1938 these rock formations have been included in the Register of protected territories and protected areas in Bulgaria.
