The Hellenic Cultural Museum was dedicated on May 3, 1992.  The museum located on the lower level of the Holy Trinity Cathedral is the first Greek ethnic museum in the United States, and represents more than $100,000 in donations and in-kind services.  The primary emphasis of it's collection is on Greek history (classical & modern), Eastern Orthodoxy, comparative religions, and Greek-American history.  The idea for the museum dated to May 23, 1986, with the establishment of the Hellenic Cultural Association, under the stewardship of Chris Metos. 

The origin of the museum began with the concept of creating a repository of old photographs of Greek-immigrant activities in Utah.  In the early 1980s, a small group of native-born Greek Americans started collecting and identifying old photographs.  The collection has become a repository for archival materials.  Included are various artifacts, oral history interviews, and videos of immigrant and family activities.

The goal of the association was to establish a museum "to preserve the rich history, heritage, and traditions that reflect the Greek experience in the Intermountain West, particularly in Utah."  Toward that goal, numerous parish families donated memorabilia to the museum.  The association also was anxious to find a permanent home for "The Greek Exhibit" which had been on display at the Utah State Historical Society Museum during 1982-1984.  The museum is a "People's Museum."  It has become a major attraction during the annual Greek Festival.

The museum was honored in 1992 when it was the recipient of the Utah Heritage Award given by the Utah Heritage Foundation.  In 1994, it received a certificate of commendation from the American Association of State and Local History.  It was the only ethnic museum honored that year.  On January 18, 1996, during Utah's Statehood Centennial celebration, the Utah House and State Senate passed a commemorative resolution honoring the Hellenic Cultural Museum.

Some of the museum's collection includes a wall of early church events and community life - Easter services, a priest and his Presbytera, choir, wedding, and a funeral.  Additionally, another wall of the collection is of early Greeks in city parades, at work in bars, cafes, in front of Castle Gate Mine, etc.  The museum's north wall is the largest, so it accommodates not only weddings, but also military service pictures.  Finally, here or there on a wall you would find photographs of Greek school classes, dance groups, and sport teams, and even the canyon picnics of Cretan organizations.

The main room entrance gallery has display cases with religion and the world of work artifacts, as well as a collection of over 60 Greek dolls in their native regional dress. In front of the doll display cases stands a replica of the small scale preliminary statue of 'Lycurgus the Lawgiver'.  However, the premiere exhibits are two of the collection's largest artifacts: the church bell from the south bell tower and, the original dome icon canvas (Pantokrator - Christ Almighty).  Inside the exhibit room a visitor finds a wide assortment of home life artifacts ranging from a trunk brought across the Atlantic in the early 1900's to an Olympic volunteer jacket from the 2002 Salt Lake City Winter Olympic Games.  Also in the exhibit room the visitor can spend time flipping through the carousels to read newpaper stories with a Greek twist.  In conclusion, there is one case in that room that displays the vestments of Rev. Fr. Elias Stephanopoulos, who served the Salt Lake Community in the 1960s.
