Tsitsernakaberd is the official memorial to the Armenian genocide victims in Yerevan, Armenia. It was opened in 1967 after a mass demonstration that took place in Yerevan on April 24, 1965, on the 50th anniversary of the deportation of hundreds of Armenian intellectuals from Constantinople that marked the beginning of the Genocide. After Armenia's independence from the Soviet Union in 1991, the memorial became part of official ceremonies. Since then, almost every foreign official who visited Armenia included a visit to the memorial to pay tribute to the victims of the Armenian Genocide. A visit to Tsitsernakaberd also includes a tour in the museum. Some notable visitors have planted trees near the memorial.
