The Navy is unveiling nine new signs this week that explain historical naval sites at Pearl Harbor.

One of the new wayside exhibit markers highlights the naval hospital that once occupied the area known as Hospital Point.

The 74-bed hospital admitted its first patient in 1917.

A Japanese plane crashed into the tennis courts just behind the hospital’s laboratory during the Dec. 7, 1941 attack.

The hospital is no longer there, but historic homes remain.

The Navy is due to unveil the wayside exhibits on Thursday.

That’s the 112th anniversary of the date when President William McKinley authorized the establishment of the U.S. Navy Hospital Corps.
