Budapest District XVII

District XVII of Budapest (known as Rákosmente) is a suburban district of Budapest on the left bank of the Danube, in the eastern part of the capital. It is Budapest's largest district, with an area of 54.82 km2, and home to nearly 90,000 people, making it the seventh most populous district of Budapest. Towns that were different in nature, but closely connected, were annexed to the capital in 1950 as part of the Greater Budapest plan. It is one of the most beautifully located districts of Pest, which is partly located as high as the 235 meters Gellért Hill. As the district is part of the Pest Plain, which gradually rises from the Danube to the east, the district's area is almost entirely hilly. The 241 meter high Erdő Hill, the highest point of the Pest side and the Pest Plain is also located here.
