Fisherman's Bastion

"Fisherman's Bastion Fisherman's Bastion was built between 1895 and 1902 on Buda's Castle Hill not to provide protection, but rather as a lookout point—and this fairy-tale castle site, with its seven spired towers representing the seven tribe of Magyar (Hungarians) that settled here in the 9th century, is all about providing stunning views of the city, the Danube, and best of all the ornate parliament building across the river. In medieval times, a guild of fishermen protected this area, giving the bastion its name, and its construction coincided with the restoration of the nearby church. You can just walk around and drink in the beauty, or pay a small fee for a walk up a tower spire, to further amplify the amazing view."

ok obviously you're going to go here because it's a big tourist place. however my biggest tip is to go at night, after sunset for sure. then you don't have to pay to actually go up on the walls & you get to see the city at night which is so sweet. there's way fewer people and it's great for pictures as well as getting that good travel feeling (yknow when you feel adventurous and independent and all that)
