the missing parts, and exhibited with two monoxyls. In April 2021, discovery of other vessels was announced. They were discovered in the former arm of the Danube, buried deep into the clay sediments, which indicated a period older than Viminacium's golden age. The largest ship is long, and the total of seven vessels was discovered, in various shapes and sizes. Some pottery was found, too. Carbon dating showed that the oldest ships were from the 1st century B.C., while some originate from the 15th and 17th century. They were all made of oak, and the iron cramps used to bind the wood survived. The recent ship discoveries point to the former, apparently abundant, oak forests in the area, and over a millennium old, previously unrecorded, shipbuilding tradition which both predated and survived Viminacium. Domus scientiarum Viminacium Domus scientiarum Viminacium is a new scientific, research and tourist center built on the edge of the Archaeological park. The Domus was constructed in the manner of a Roman villa, with rooms and laboratories grouped around several atria. The Domus hosts an archaeological museum, a scientific library, laboratories for processing archaeological finds, an information center, conference rooms, a restaurant with dining hall and SPA center in the form of a Roman bath. There are also bedrooms available for researchers, students and visitors. One of the most spectacular features is a large conference room decorated by a Serbian mosaicist who installed mosaics based on Late Antique style. The bedrooms are styled after the Roman military barracks and have six beds in one room. The complex became an archaeological congressional center, labeled the "congressional (military) camp" which includes the central plaza, two debating halls and the large dining room patterned after the Roman military mess halls. When not used for the scientific gatherings, the part of the complex adapts into the "Roman children camp", with the adjoining adventure park partially made after the Roman training grounds for the legionaries. Some of the experiments include attempts to recreate other practices done in the "Roman way", like cremations or planting grapevines. The Limes Park, a recreated Roman training ground was finished in September 2018 while the adjoining adventure park was open in December 2018. It covers an area of and consists of 48 attractions. In 2017 Viminacium had 100,000 visitors, the largest number of tourists in its history. Of that number, 17,000 came via boats as the pier
