On September 3, 1864, the theatre at 37 Bowery became known as The Varieties, making variety shows its main draw. This form lasted until mid-October 1865, when A. Montpelier became the manager and owner. He renamed the building Montpelier's Opera House, although he kept its emphasis on variety and melodrama. Montpelier changed the name once more on November 20, 1865. The New National Circus stayed open for six weeks for its final stint as an entertainment venue. The structure was converted into an armory in 1866.
