Overview of Yokohama Port Opening Memorial HallThis building, beloved as a red brick clock tower, wasconstructed in 1909 through a public design competition tocommemorate the 50th anniversary of the opening of
Yokohama port, and was completed in June 1917.
In the Great Kanto earthquake in 1923, the roof and interior
were burned down, leaving only the exterior walls. It wassubsequently rebuilt in 1927, but the copper dome wasomitted and the interior was somewhat simplified.
Although it escaped damage during the war, it wasrequisitioned by the US military from the end of the waruntil June 1958. Later, due to its deterioration, it faced thedecision of whether to preserve it or demolish it, but it wasrepaired in 1978, and the dome was restored in 1989,
restoring it to its original appearance. Currently, it isdesignated as an Important Cultural Property by thenational government as a representative building of theTaisho period, and is used as a public hall for Naka Ward.
