Portland City Hall is the fourth city hall built in Portland. It was built between 1909 and 1912 and was listed on the National Register of Historic Places in 1973.
The earlier hall, designed by Francis H. Fassett and built in 1867, burned in 1908. The one before that, built in 1862, burned in the Great Fire of 1866. The new building was designed by New York firm Carrère & Hastings, with local help from John Calvin Stevens and John Howard Stevens.
Its granite tower is 200 feet (61 m) tall. John M. Carrère, who was inspired by New York City Hall, considered it one of his finest works. The addition on Myrtle Street includes Merrill Auditorium, home of the Kotzschmar Memorial Organ.
