In August 2021 it was announced that city's Institute for the Cultural Monuments' Protection is conducting a study on declaring the Topčidersko Brdo-Dedinje area a protected spatial cultural-historical unit. Municipality The municipality of Topčidersko Brdo was formed after the previous division of Belgrade into districts (rejon, 1945–52) abolished. It comprised the two wealthiest neighborhoods of Belgrade, Senjak and Dedinje. Following the new administrative reorganization, Topčidersko Brdo merged with the municipality of Zapadni Vračar to create new, still existing municipality of Savski Venac. After the abolition of the municipality, Topčidersko Brdo remains mostly a geographical rather than administrative term even though it makes one local community within Belgrade with Senjak (Topčidersko Brdo-Senjak) with a population of 7,249 in 2002.
