Taken from Castle Hill, not quite the Fishermen’s Bastion (judging by the perspective), but nice anyway.
Here’s a link to a larger version.
All the bridges were blown up by the Germans as they retreated west from Pest to Buda and the fortifications on the hill when the Red Army entered the city.
Here’s a nice reference from Google Maps. Pest (what you’re seeing in this picture) is to the right of the Danube, the river running from top-to-bottom in this map. Buda is to the left of the Danube. Pest’s streets are more gridded because Pest is on flat land, part of the Great Hungarian Plain. Buda and (to complicate) Obuda, are built on hills.
