Behind the monumental Egyptian Revival façade of the Consistory Shrine Temple, still standing today, is one of Helena's best-kept historical treasures: the interior of the 1880 Ming Opera House. The theatre was acquired and modified by Helena Masons in 1912; in 1915 the façade, designed by architects George Carsley and C. S. Haire, was added.

Next to the Consistory Shrine is the 1903 Helena Light and Traction building at 19 North Jackson, also still standing. It housed an electrical substation (where voltage is transformed) that operated until 1951, when an outdoor substation was built at 651 Front Street. The Front Street substation was removed in 2004, and replaced by a larger-capacity station near Bill Roberts Golf Course.

Farther north on Jackson is seen part of the 1897 Rocky Mountain Telephone Company building.

Here's a beautiful circa 1915 view looking north on Jackson Street from Broadway. On the left is the rear of the Gans & Klein building, which fronted Main Street. On the right, still standing today, is the 1885 Masonic Temple building, which for many years housed a printing house on the ground floor.
