The plan for a clocktower at the foot of Fort Street above the terminal complex at Piers 8, 9 and
10 of Honolulu Harbor was first made public in 1919 as part of a larger harbor modernization
project.

After years of debate concerning the style and height of the tower, the Board of Harbor
Commissioners began construction in 1925, and it was completed in 1926. Originally slated to be
172 feet tall, designs for the tower were changed during construction to add an additional story
making the tower 184 feet tall with a 40-foot-tall flag pole and four-foot time ball on top.

The tower
was to serve as a lookout for the harbor master and harbor pilots, with offices below for other
Board of Harbor Commissioners activities. Unused office space was available for rent to local
businesses, and the tenth-floor observation deck was free and open to visitors.
During Hawaii’s time as a U.S. territory, the Board of Harbor Commissioners was responsible for
shores, streams, harbors, and wharf and pier construction throughout the islands.

The board
was pivotal in modernizing Honolulu Harbor, primarily through canal dredging and wharf
construction, which allowed more and larger freight and passenger ships to access the harbor.
Aloha Tower was a major part of the harbor improvements. In addition to its role as a lookout
point for harbor pilots, the tower was outfitted with a time ball that helped mariners “in setting their
time and adjusting their chronometers,” as well as a siren that sounded three times a day.
11
Later,
a naval-style yard arm with a ball and cone communication system was added to the tower. “When
an orange ball and cone were both displayed, the harbor was closed. Right-of-way belonged to
incoming ships when just the ball was displayed, and outgoing ships had the right-of-way when
just the cone was present.”
12
In 1926, the Honolulu Harbor light at Sand Island was retired, and
a newer light was installed at the top of Aloha Tower.
13
The new light was more visible than the
one on Sand Island and shone atop Aloha Tower until the late 1960s when it was moved to a
taller television tower.

Aloha Tower served Honolulu Harbor not only as the Harbor Master’s office and official traffic
control for the port, but also as a transportation hub and signal of welcome to visitors. The bright
white Aloha Tower was the tallest building on the Hawaiian Islands for many years and was one
of the most distinguishable man-made features of the Honolulu skyline. After five days at sea,
passengers disembarked their ships at the terminal complex on Piers 8, 9, 10 and 11 with the
Aloha Tower above them. From its construction in 1926 until the marked decline of passenger
ship travel in the late 1950s, the Aloha Tower was the first place many visitors to Hawaii set foot.
The arrival of passenger ships at Piers 8, 9, 10 and 11 was always met with a Boat Day
celebration. Originally an irregular event focused on the arrival of mail and goods from the “outside
world,” the Boat Days tradition was kept alive in the territorial era by Matson Navigation Company.
Matson employed the Royal Hawaiian Band to play traditional Hawaiian songs while local women
danced hula and sold leis to visiting guests at the foot of the Aloha Tower. Though Boat Days
