I climbed to the top of a hill in Gellérthegy where there's a little observation point (Uránia Observatory, in fact). So I observed. The building on the left in the picture (with the copper-green dome) is the old Royal Palace on Castle Hill. The small peaked dome in the middle of the picture, on the opposite side of the Danube, is the Parliament building. A little bit of the Danube and Erzsébet híd (Elizabeth bridge) can be seen near the right.
