In the spring of 1876, poet and revolutionary Hristo Botev, an emigre in Wallachia, decided to gather an armed band, to cross the Danube and to join his fellow Bulgarians' April Uprising against the Ottomans. He managed to realise his plan thanks to a bold action - his men boarded on the Austrian-Hungarian steamboat Radetzky dressed as ordinary itinerant gardeners, and on 18 May seized the ship. Then they made the captain to bring them to the Bulgarian bank of the river, by Kozloduy. From here on, they started their heroic, yet doomed, march through the Danubian Plane that ended with the death of Botev and most of his men.

The first memorial on the site of Botev's landing by Kozloduy was put there in 1878. In 1939, a larger memorial was erected onsite. However, the most intriguing part of the location is the replica of the steamship that Botev used to cross the river.

The original steamboat was sent to scrap in 1924, but in the 1960s Bulgarian children started a national donation campaign that aimed to fund the construction of a replica. The new Radetzky was built in Ruse's shipyard in 1966. The steamer works and takes off regularly (for groups of over 50 people) It is managed by the National History Museum.
