Budapest's Danube River level dropped to record lows this week, reaching 23 centimetres on Wednesday (29 July). The previous lowest water level, 33 centimetres, was recorded in 2018.

By Wednesday lunchtime the water level had risen slightly, to 25 centimetres, but no significant improvement is expected. What is more, the summer’s second major heatwave is just now reaching Hungary.

As the Danube recedes, more and more of the riverbed is being exposed. The situation is so extraordinary that the president of the Hungarian Cyclists’ Club, Gábor Dezső Kürti, was able to cycle along the riverbed all the way from Budapest to Vác. A few days ago, a Euronews reader came across a strange, perfectly shaped stone on the riverbed near Visegrád, which immediately caught his attention.

The reader also informed the Mátyás Király Museum in Visegrád about their discovery, and on first look it appears it could be a catapult projectile.
