This wreck used to be a big paddle steamer called "Blond Tisza" which was built in 1917 and later reused as a restaurant & bar for 20 years from 1979 and then fell into disrepair. Some sources claim it to be the biggest Hungarian river steamboat ever built. In 2020 January it was rescued from complete rotting after it was dragged ashore. See the nice time-lapse drone video linked.
