Portland City Hall is the headquarters of city government of Portland, Oregon, United States. The four-story Italian Renaissance-style building houses the offices of the City Council, which consists of the mayor and four commissioners, and several other offices. City Hall is also home to the City Council chambers, located in the rotunda on the east side of the structure. Completed in 1895, the building was added to the National Register of Historic Places on November 21, 1974. City Hall has gone through several renovations, with the most recent overhaul gutting the interior to upgrade it to modern seismic and safety standards. The original was built for $600,000, while the 1996 to 1998 renovation cost $29 million.

In the early morning hours of November 21, 1970, a dynamite fueled bomb exploded underneath the portico, doing $170,000 in damage. Though no one was injured, windows were blown out, the Council Chamber (located above the blast) was damaged, all of the columns of the portico were damaged and replaced, and the Liberty Bell replica was a complete loss. A new bell was purchased for $8,000 and later moved to Terry Schrunk Plaza. No one was ever arrested or claimed responsibility for the bombing.
