Tamanian incorporated national traditions with contemporary urban construction . His design presented a radial-circular arrangement that overlaid the existing city and incorporated much of its existing street plan . As a result , many historic buildings were demolished , including churches , mosques , the Persian fortress , baths , bazaars and caravanserais . Many of the districts around central Yerevan were named after former Armenian communities that were destroyed by the Ottoman Turks during the Armenian Genocide . The districts of Arabkir , Malatia-Sebastia and Nork Marash , for example , were named after the towns Arabkir , Malatya , Sebastia , and Marash , respectively . After the end of World War II , German POWs were used to help in the construction of new buildings and structures , such as the Kievyan Bridge
