If you’re planning a trip to Pearl Harbor, don’t expect the USS Arizona Memorial to be part of your itinerary. Due to structural issues, the ship’s memorial will remain closed indefinitely while repairs are made. After a crack was spotted in the monument’s outside walls, boat transportation to the site was halted on May 6th.

The famous battleship USS Arizona was among the first ships bombed during the Japanese attack on Pearl Harbor on December 7th, 1941. Over 900 sailors and marines perished with the ship. In remembrance of the attack and the crew who died, a memorial was constructed on top of the sunken ship in 1962 by Honolulu architect Alfred Preis.

It’s estimated that 1.8 million people visit the USS Arizona Memorial every year, but, even with the memorial being repaired, visitors will still have plenty to see at Pearl Harbor. There is a free narrated boat tour of Pearl Harbor that passes alongside the sunken ship and a 23-minute documentary film prior to boarding. The National Park Service releases 1,300 free tickets for the tour every morning at 7 AM, at the ticket counter, on a first-come-first-serve basis. There are also several other free museums, such as the Battleship Missouri Memorial, USS Bowfin Submarine Museum & Park, and the Pacific Aviation Museum, which are still open to the public, and are sure to keep visitors entertained.

The National Park Service has no timeline for the memorial’s reopening, but updates will be posted on the monument’s official website.
