“This much-needed work will ensure the Ahwahnee is seismically safe for present and future generations of Yosemite visitors,” park Supt. Cicely Muldoon said in a statement.

The project is funded by the Great American Outdoors Act, the park said, and will require the historic hotel to shut its doors from Jan. 2 to March 2. On Wednesday, the hotel’s website was already warning would-be guests of the closure.

The work will include bracing chimneys and walls, the park said. The hotel will also get a kitchen renovation and upgrade to its heating and air conditioning systems.

Built in the 1920s, the hotel is located near some of the park’s most popular attractions, including Half Dome, Yosemite Falls and Glacier Point. The hotel has hosted dignitaries and royalty, including Queen Elizabeth II and Prince Philip, and Presidents Kennedy and Obama.
