In the middle of the Danube lies the Margaret Island, also called Margit Island. It is almost 3 kilometres long and at its widest point 500 metres wide. On this island there is no motorized traffic with the exception of buses and taxis. It is a green oasis in the heart of the city with some unique sights.
The name comes from Margaret of Hungary, the daughter of King Béla IV, who lived in a monastery on the island. There's not much left of that convent but a ruin. In its time the island was much smaller, it got its current shape at the end of the 19th century. In regulating the Danube, three islands were then connected and raised.
The park on the island consists of old trees, flowerbeds, lakes and beautifully landscaped gardens. There are also swimming pools, spas, a water tower and an open-air theatre. There is also a monument that commemorates the association of the districts of Buda, Pest and Óbuda.
You can reach Margaret Island from the Árpád Bridge (north side) or the Margaret Bridge (south side).
