On 27 June 1977, the Seoul Metropolitan Government suggested that the city of Seoul and Tehran, pre-revolutionary Iran exchange the names of streets on the occasion of the visit to Korea of Gholamreza Nikpey, Mayor of Tehran. The following year, "Samneungno" street was renamed Teheran-ro (translation: Tehran Boulevard), Seoul Street's Korean counterpart, which then ran through a relatively underdeveloped area that been annexed into Seoul in 1963, which then experienced phenomenal growth and waves of construction. Today, Tehran Boulevard is colloquially known as "Teheran Valley" (after Silicon Valley) due to the number of internet-related companies operating there, with Teheran-ro becoming one of the busiest streets in South Korea.
