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 Erivan 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.
