The numerous travertine barriers and waterfalls along the Una River are what make Martin Brod famous. Milanev buk, a waterfall with a height of 50 meters, is located on the most stunning and interesting section of the river Una. The Unac tributary enters the river Una at Martin Brod as well. There are a lot more pools, cascades, and waterfalls visible as well. Martin Brod has earned a reputation for building grain-grinding watermills on the Una River throughout history. Along with the mills, Martin Brod also owns several “bunica,” or vintage eco-machines. There used to be more of them, but there are now just few. The Rmanj Monastery is visible at the town’s entrance. It has a church and other buildings and was constructed in the fourteenth century. The enigmatic seal, which is the village’s actual name, is named after the charming and young Marta from the story of forbidden love. She died as a result of her bravery in the struggle for love, which defied all conventions, leaving behind a fascinating tale that continues to captivate people today.
