1890 – Opening of the park. For the first summer, the Theatreorium — as it was originally called — was little more than a 12-sided tent with rows of chairs.
1891 – Theatre opened for the summer. While it was originally open on all sides, this was the general structure that still stands today.
1893 – Some sources consider 1893 to be the first year of summer stock at the Theatre, but others consider 1897 to be the first year. In 1893 the Frank Norcross Company was hired for the full season, so it can be considered a regular summer stock cast, but in 1897 a resident summer stock company was formed as the Elitch Gardens Theatre Company.
1894 – The ‘Anne Hathaway Curtain’ was installed and remained hanging in the theatre for nearly 100-years. (Painted by Charles F. Thompson Scenic Company of Los Angeles.)
1896 – Thomas Edison shows his new invention, the Vitascope, in the theatre. These are the first films shown west of Chicago.
1897 – The Elitch Gardens Theatre Company is formed, making the Elitch Theatre the first Summer Stock theatre in the country. For over 60-years the theatre would hire a stock cast to play for the entire summer. Additionally, box seats were added to the theatre. (Originally there were 12 box seats, but in 1899 two of the lower boxes were removed and then in 1923 two of the upper boxes were removed.)
1899 – To start the season, “zoological” was dropped from the name of the park and it officially became known as “Elitch’s Gardens”. Then, starting in the winter of 1899, and continuing for several years, some major improvements were made to the theatre.
1904 – Several major rides were added to the park: a “Figure Eight” roller coaster, the Old Mill, and a “Circle Swing.”
1905 – The original park carousel was purchased from the Philadelphia Toboggan Company and is know as PTC#6 (the sixth carousel they built.)
1909 – The original “log entrance” was replaced by an ornate, Greek-Revival styled stucco gate.
1916 – Mary Elitch sells Elitch Gardens and the Theatre. After a short period of ownership by John K. Mullen, John Mulvihill purchased the park and his family would run it for the next 80-years.
1917 – The Trocadero Ballroom is added to the park. (There was an earlier venue at the park known as the Trocadero, mentioned by Mary Elitch in her biography and also mentioned in a June 6, 1909, Denver Post article, but its location and layout is unknown. Mary describes it as a venue for orchestra concerts and free afternoon vaudeville shows.)
1918-1919 – Theatre closed due to recession and world war one.
1923 – Before the opening of the 1923 season, several major renovations were completed:
1928 – The original carousel (PTC#6) is sold to Kit Carson County in eastern Colorado where it is still in operation today. Elitch’s Gardens’ new carousel, PTC#51, took master craftsmen three years to carve by hand and it is still in operation at the amusement park today.
1936 – Mary Elitch passes away.
1940 – The first floor seats were replaced with new leather upholstered seats (which remain there today!)
1954 – This year saw some significant changes to the theatre (and to the park.)
1958 – Due to the widening of 38th Avenue, the stucco entrance had to be removed and it was replaced by an art-deco aluminum arch.
1975 – The Trocadero Ballroom is torn down to make room for more rides.
1978 – The Theatre is added to the National Register of Historic Places.
1987 – The final regular season of theatre was the summer of 1987. The season opened with Nunsense, and when it was clear that there would not be another season, they brought the crowd-favorite Nunsense (and Denver native, Mary Jo Catlett) back to close out the theatre.
1991 – To celebrate the 100th Anniversary of the theatre they re-opened for a special run of the show, The Robber Bridegroom.
1994 – The last summer of Elitch Gardens Amusement Park in NW Denver.
1995 – The new Elitch Gardens opened at the downtown location. At the same time, Denver City Council unanimously designates the theatre at the original location as a Historic Landmark.
2002 – Historic Elitch Gardens Theatre Foundation (HEGTF) formed to pursue the restoration and preservation of the theatre.
2007 – Roughly $5 million dollars was raised for Phase One of the restoration, which included the meticulous — historically-accurate — reconstruction of the exterior of the building.
2012– Phase Two began with a budget of $600,000+ to complete interior upgrades, including the addition of lighting, plus health and safety upgrades which included the installation of a fire-suppression system.
2020 – Following a 2018 storm that caused approximately $800,000 in damage, the organization used insurance money, a grant from Denver Urban Renewal Authority, and a grant from the State Historic Fund to complete Phase Three, which included a new roof, new restrooms, interior painting, and exterior landscaping.
