the original project of Nikola Tesla, patented in 1913, using a pump which uses very little electricity. It took 25 years for researchers to fully understand Tesla's idea and create a fountain like this. At the time, Tesla collaborated on the design of the fountain with the famed US stained glass artist Louis Comfort Tiffany. Students Polyclinic On the corner with the Braće Nedić street, one of the "most elegant" buildings in Belgrade was built in 1923/1924, with the purpose of being the largest and the most modern privately owned health institute in the Balkans. During the heavy "Easter bombing" of Belgrade by the Allies on 16 April 1944. the hospital was hit and over 50 people were killed, including 22 mothers and 22 newborns, several visiting family members and several medical workers. Since the mid 1950s the "Institute for the student's health protection Belgrade" has been located in the building, which is colloquially known as the Students' polyclinic. Memorial plaque for the 1944 event was dedicated on 16 May 2017. In February 2021, the new master plan by the Ministry of Health envisioned abolishment of the student polyclinics, and their annexation to the regular, community healthcare centers. Negative backlash, both by the citizens who rejected an instant influx of 100,000 new patients into the regular healthcare system which is overstretched as it is, and by the students, resulted in the petition of 35,000 signatories in only two days, and protests by the students in front of the ministry building. Minister Zlatibor Lončar verbally clashed with the students accusing them of being political, but both he and the prime minister Ana Brnabić then announced that the plan will not be implemented and that students medical centers will remain as they were. Protection The neighborhood was placed under the legal protection in May 2021 as one of Belgrade's spatial cultural-historical units. Protected area includes the streets of Topolska, Petrogradska, Krunska, Vojvode Dragomira and sections of Mileševska, Maksima Gorkog and Novopazarska. The area was described as the "part of the wider city center, mostly residential, which was formed in the first decades of the 20th century. The area and the individual buildings have cultural, historical and architectural values, as testament of the urban, economic and social development of the capital during Interbellum, but also of the certain style of living of its residents."
