Castle Hill (Várhegy) and the Citadel (Citadella) At one time Buda and Pest were two different cities. Buda has a much longer history than Pest but both have great bragging rights even though they have been ravaged many times. Buda, Óbuda and Pest were united in 1873. Castle Hill (Varhegy), the Citadel (Citadella) and the Liberty Statue are good places to start when learning about the city. They are up the hill from the Danube River on the Buda side.
