The 50th Anniversary of the October Revolution Monument, Soviet memorial monument in Arabkir District, Yerevan, Armenia

The 50th Anniversary of the October Revolution Monument is a 50-meter-tall tetrahedral obelisk topped with a golden leaf, surrounded by rectangular platforms arranged along two intersecting axes. This geometric composition creates multiple viewing angles and spaces for movement throughout the site.

Built in 1967 by architects Jim Torosyan and Sargis Gurzadyan, the monument marks five decades since the October Revolution in Soviet history. A memorial complex was added in 2008 to honor Armenian citizens who faced repression during the Soviet period.

The obelisk's base carries traditional Armenian ornaments, including the arevakhach eternity sign, and motifs drawn from Urartian architecture. On the south face are carved lines from Yeghishe Charents's poem "Frenzied Crowds"; the north face gives the opening year 1967 as "ՌՋԿԷ", written in old Armenian letters instead of digits. A memorial hall west of the obelisk honours victims of repression.

Located at the start of Azatutyun Avenue, the structure includes viewing platforms offering sightlines toward Mount Ararat and the Yerevan skyline. Visitors can walk through the different levels comfortably and find clear vistas from multiple spots.

The golden leaf crown was a bold architectural choice for the Soviet era, creating a distinctive silhouette against the sky. This tapered form sets it apart from other Soviet memorials that typically feature heavier, more imposing designs.
